Innovation in Technology,
Key to the Growth of the Gems & Jewellery Industry
      Technology Giants Earmark Investments in Research and Development

The global gems and jewellery industry has been growing at an astronomical pace in recent years, thanks to the importance given to key sectors such as Research and Development in the Technology and Machine tools segment by well known companies. Research and Development has not only resulted in the development of innovative techniques but also has elevated the gem and jewellery industry to the highest level of quality and precision. Technology and Machine tools have changed the way not only a manufacturer looks at a final product, but also has affected consumers’ preference. Today every consumer is looking at finesse and exclusivity in the product that he buys and is also willing to pay a premium for the same. Leading Jewellery designers of the world have acknowledged the role of technology in jewellery making and today most of the designs are exquisite only because of the interference of technology in the final product. Every technical process from Mine to Market involves technology and Machine tool expertise, be it refining of precious metal, to polishing of the precious stone, or moulding and setting involved in jewellery making. Packaging too has evolved and is playing a vital role in the sale of jewellery, all thanks to the advent of innovation in technology.

Jewellery industry is probably only second to Information Technology sector [IT] when it comes to investment in Research and Development. Leading Machinery, Technology and Education companies of the world from the jewellery sector are earmarking huge investments in their respective R&D departments for continuous research and come out with state of the art tools that not only will save time of production but also help in accurate determination of the ‘subject’ which in turn will determine perfect ‘pricing’ of the final product. Be it Gld, Platinum, Diamond or Color gemstones, Technology helps in determining the product quality, achieve finesse in production which saves time, effort and money in the process of manufacturing and ultimately helps derive pricing of the finished product.

Some of the classic examples of recent Research products are ‘Synthetic Diamond determination Machine, introduced by GIA, Diamond counting machine by HRD Antwerp, Rhodium processing technology by Nadir Metals Turkey etc. These innovations have truly transformed the very essence of manufacturing by easing out many a process involved in the production of a finished product. Global consumers are getting a taste of the best quality and exclusively crafted products which is now a norm. Technology has also compensated the growing Gold rates and Diamond prices by intervening the production process. Light weight Jewellery is a result of cutting edge technology. Leading manufacturers of the world have been successful in launching ‘light weight jewellery products’, be it chains, necklaces, bangles or any other due to the usage of highly quality precision equipments. Light weight jewellery have also become the most sought after by budget consumers. Diamond wastes due to cutting and polishing have also found good use in the making of jewellery. In this story the JTM bureau has profiled important companies in the Technology and Machine tool segment, some of whom with sheer passion for research and development have introduced state of the art products that would go a long way in transforming the Global Gems and Jewellery industry.

The matrimony between
High-tech and traditional tools
Since many of years the diamond manufacturing industry has been an industry were craftsmanship took an important place in the creation of a perfect diamond. However, the last 20 years, more and more high tech tools, such as rough and polished planners, laser sawing and shaping machines, gemmological instruments and auto blocking devices , succesfully earned their place in the proces. One might say that total automatisation of diamond manufacturing is nearby. This could be if the quality standards of the polished diamond would have kept their old values. But the market requests higher quality of make. Triple-X, flawless cut, with an impeccable smoothness are nowadays the key words. This sets the bar high, aspecially on the finishing or brillanteering side. There is no device yet wich can replace the soft touch, the sensitive reaction or the apprehension of the human hand and mind. The workers skills makes half of the result, a perfect polishing tools provides the second half. Let's put it this way, a precious diamond deserves only the best of polishing tools. Since over 65 years, Rico Tools Belgium fulfils this commitment.

In the late sixties, RTB launched with great succes the first Rico dop with endless facet screw, a big improvement for its time. Many changes later the D265 series (excellent dops) and the D420 series ( Quick Step dops) have proven their reliability in a large number of factories the world over. We at Rico Tools Belgium believe that their always will be room for the traditional equipment in a perfect joint venture with the automated tools. It is still an trilling idea to know that part of your precious diamond is created by the hands of a artisan. Located in Belgium at the cradle of the diamond industry, Rico Tools is a third generation company with a broad experience and a strong reputation.

Mechanisation & Automation
is the call of the Day

S. Tirupathi Rajan
MD - Goldsmith Academy Pvt. Ltd.
Jewel to every consumer in the world means that it adds to their personality that improves ones outlook besides that it is also reflection of tradition, culture, ritual and represents many symbol and beliefs in India. The change in the modern jewellery market though has extensively differentiated the purchase experience for the consumers, but it has less differentiated the expression in terms of designs of the jewellery; this also could largely mean that our Indian craftsman has given to the consumer, especially women, who constitute more than 90% of the user, unlimited designs and tastes in the past; the only variation in the jewel taste of Indian women is that the role of daily use is ever increasing as compared to occasional use of jewels in the past, which therefore leads to usability as a frequent wear, to be more; this means that more ornaments for less gold (as in line with any other consumer behavior “more for less”); that has forced the traditional artisans to many challenges in the modern manufacturing of gold jewellery for Indian women.

The market is taking a balance in the multidimensional forces: price or cost, ability to buy, design variations, volumes, refurbishing or exchanges and marketing. The only solution to maximize the business of craftsman or goldsmith or the manufacturer amidst these forces is the Technology. Technology plays role in all cycles of jewellery manufacturing: designing, melting & drawing, refining, dye or mould making, casting, testing and fixing, electro plating, enameling, carving & stone fixing, assembling; consumers want even virtual simulation of the suitability of the design to her before even the production for which software’s are extensively available; as the market is open consumers want absolute transparency and freedom to trade her product without getting locked to a vendor or retailer, there comes the BIS standards and the technology such as measurements such as weight, metal composition and assessment without destructive testing have proven to be highly possible and viable using laser scans. To be more categorical, machineries – mechanical, electrical, electronic including software applications – are essential element for anyone in this market to be sustainable and profitable.

The days are not too far to say the as we have in food industry – ready to cook or eat – or just in time paint manufacturing or tailor made garments - we will soon see the days of design to product in minutes or hours as tailor made becoming an option for new market space in Indian consumer markets using rapid prototyping or manufacturing machines available in the retail counters at their backyard workshops. Soon adaptation to technology will be the underlying vehicle for any skilled artisan or manufacturer or retailer in this market in India, which will behave differently from any gold jewellery market in the world, unlike many industries are impacted by westernization but jewellery will not be. So start and go for mechanization and automation as much as you can. Every Rupee investment will get you 30% more cost savings and profit improvement in your business.
While doing so technology transition becomes a big challenge for the players. In jewellery industry in India transition works in 5 steps; education, trials, implementation, improvement and proficiency; generally it takes 2 years of sustained effort by oneself to reach the proficient level of using technology in this trade. However transition has a cost which has to be treated as investment by the player rather not to look at it with short sightedness. With gold price going up always in long run, as with economy, it must be noted by the player that the transition cost will be very less today as compared to technology transition cost after few years; this is a major difference between the jewellery industry and other traditional as well as modern industries. So why wait?

It is recommended for every player, which most of them are in traditional manufacturing or trade practices, to take an experienced consultant; we strongly recommend to the industry to adapt lean manufacturing as well as kaizen principles in their operations, no matter of their size or level of operations. The transition investment shall be more optimal if the transition are planned and designed along these lines.

Goldsmith academy is committed along with Friday Micro Ventures for the welfare of the traditional jewellery manufacturing industry in India for the competitiveness of the millions of goldsmiths in the modern market. You can

GARG ELECTROHEAT
A Trusted Name in the Field of Jewellery


Jewellery is a very fascinating term. It has a lot of sparkle in it. It is a fashion statement for ladies and a matter of fortune for gentlemen. Do you know a lot of labor, creativity and hard work go in making these beautiful pieces of art? It all starts with melting of precious metals like GOLD, SILVER etc.

Jewellery is not manufactured with 100% Gold or Silver. These metals are very soft and some alloy additions are required to increase hardness and other properties. Garg Electroheat are importers and sole selling agents of Gallorini brand alloys and solder powders from Gallorini snc, Italy.

Jewellery manufacturing is associated with metal refining to recirculate old metal and the scrap metal.

Garg Electroheat represents Italimpianti Orafi spa, Italy for their refining and casting machines.



It is seen that LPG is used for jewellery production in the form of soldering and brazing torches. This method of soldering and brazing is very hazardous for workers as well as very risky for storage. A very environment friendly way to generate flame is from disassociation of water in oxygen and hydrogen. If hydrogen is burnt in presence of oxygen it emits water vapors which are not harmful for health at all. Garg Electroheat are representative for McPhy Energy, Italy for their Gas Generators. Go Green.

As the value of Gold is increasing every day people have started looking for alternate jewellery. Platinum is now within reach of common people. Garg Electroheat are sole selling agents for Hot Platinum South Africa for their range of Platinum Group Metal melting and casting machines.

Imaginarium
Offering 3D PRINTING revolution in Jewellery


3D Printing is a revolutionary technology that is rapidly transforming the jewellery landscape. From design to production to retailing, the 3D Printing wave is sweeping across the industry and promises to become the de facto process in jewellery design & manufacturing. 3D Printing machines build 3D objects (rings, pendants, bangles, murtis) directly from CAD models. They do this by digitally slicing the 3D model into thin layers which the machine then builds one layer at a time to make the physical object. These models are made of a variety of plastic resins, wax, and directly castable resins. These prototypes can then be used for investment casting and other metal production processes.

3D Printing brings major advantages:

• Create impossible, never-seen-before designs or highly customized pieces, even if its just one.

• Make them in record time - hours to days only

• Save huge on development and production costs

• Develop lean and flexible business processes

New Italian and Spanish made Machines for Jewellery Manufacturers Introduced by DM IMPEX in Indian Market


With the increasing use of mechanization in different stages of the jewellery manufacturing process in India, the demand for more compact and efficient models that are specially designed to operate in Indian conditions is on the rise.

Italian-manufactured Advance Series Laser Welder

DM IMPEX who introduced OROTIG in India, has recently launched a new Advance Series Laser Welder with unique features specially customised for Indian conditions. This can be powered by 60/100/125 Joules and comes with some key features that perfectly match the needs of Indian manufacturers.

The machines are manufactured exclusively for the company by OROTIG, one of the leading Italian manufacturers of machines using LASER technology. The new machine comes with an inbuilt ‘Rapid Heat Exchanger’ that ensures faster cooling. By using the “Advance” Laser Welder, a manufacturer will be able to boost output as a result of better duty cycles. More efficient cooling also ensures longer life for the machine.

Another optional feature is the External Video connection with HD Camera. A manufacturer has the option of plugging in a lager external monitor. This means that the operator can view the work in larger size images ensuring greater accuracy in operations.

Another innovation is the stand alone “WORKSTATION” LASER welder whose height can be self-adjusted by the operator, and a non-stop power release mechanism. The LASER pulse shaping programme also offers five pre-set wave shapes which allows for greater ease of operations in the case of complex pieces and metals.

DM IMPEX also offers the 20W Open LASER marker. Thanks to its open shape, operators can more easily access the laser marking area and find it easier to use the marker. This machine is ideal for marking text, graphic patterns, drawings, images, and also to do LASER markings on curved surfaces like rings, bangles and bracelets. The marker has provisions for Suction, is good for Marking on Flats & Tops and can be used for Deep Engraving & Cutting. It can also be provided with continuous feeding mechanism as options for markings and cutting.

These machines are compact and lightweight, ideal for doing small and fine details, are fast and efficient and therefore low cost and low maintenance. They are useful both for smaller workshops, Hall Marking centres and large factories.

Spanish made ‘Zero Metal Loss’ Gold & Silver Grinding & Polishing Machines

In a highly price-conscious market like India, every manufacturer seeks to gain a competitive edge by achieving greater operational efficiency. Introduction of machines that save in terms of time, manpower, electricity, etc are therefore high on the agenda. And when such machines have built in systems for recovery so that there is Zero Per cent Metal Loss, it is clearly an added bonus.

DM IMPEX, which markets a range of products from leading Spanish manufacturer HISPANA, offers state-ofthe- art machines (GPG and PMG) which are Grinding and Pre-polishing Systems for Silver and Karat Gold Alloys. These dual action systems help the manufacturer save space and electricity. The grinding and polishing results are amazing. The labour costs are at a minimum and consumables used are low.

The newer versions of these machines (Step 2) help the operator reach recessed areas, insides, filigree and work on jewellery with stones cast in place. They do not affect the stones, enamelling and non-conductive surfaces, allow for freer designs as it follows the geometry of your design and does not round prongs or angles.

Other HISPANA products that could be used by jewellers include

Mark IV/Mark IV Plus/Mark Robot: Innovative line of wax injectors

Mininvest/Starmix: More advanced investment mixers under vacuum for gold/platinum. Solid & reliable mixers for small, medium & large productions.

Starcast/Starcast Plus: New vacuum-pressurised medium frequency casting machine

D-Invest: Equipment to remove investment from flasks and trees

Oxford Instruments India
High-end Technology to Analyse Precious Metals


Oxford Instruments India Pvt. Ltd. is a wholly owned subsidiary of Oxford Instruments Plc (listed in the London Stock Exchange) and supports key customers in industry, research and academia. Oxford Instruments India offers range of high quality products for Industrial Analysis and Nano technology. Innovation has been the driving force behind Oxford Instruments’ growth and success for over 50 years, and its strategy is to effect the successful commercialisation of these ideas by bringing them to market in a timely and customer-focused fashion.

Head quartered in Mumbai, it is one of the few companies in India to set up a demonstration lab for Industrial Analysis products where distributors and customers can analyse samples, demonstrate systems and be introduced to new technologies. This lab houses a range of analysers that span applications from metals analysis, to low sulphur in petroleum, to gold coating analysis.

In order to control costs and quality, jewellery and other precious metals items (e.g. coins, high-end cutlery) are tested for composition analysis many times over their life-time, from the raw materials to the finished product and to the recycling. The analysis is also required to verify authenticity, and determine value. The high price of precious metals such as gold (Au) and platinum (Pt) means that a small difference in their contents means a large difference in the product’s value.

Traditionally jewellery and other precious metals alloys have been analysed by fire assay. This is a highly accurate technique, but is lengthy and destructive. Samples are often sent to an off-site laboratory, and results can take days to return. Because of these disadvantages, X-ray fluorescence (XRF) is also used when certification (e.g. hallmarking) is not required, providing non-destructive multi-element analysis and results in seconds!



Oxford Instruments Industrial Analysis offers a range of analytical instruments for various industrial and research applications. Our X-Ray Fluorescence (XRF) analysers deliver simple, rapid and non-destructive analysis to identify precious metal content and toxic elements in jewellery, and for measuring the coating thickness of plated items.

With over 25,000 units installed world-wide for precious metals analysis and coatings thickness applications, the X-Strata Series of coating thickness benchtop analysers offers outstanding precision and accuracy. These compact, rugged and reliable quality control analysers can perform elemental analysis without any chemicals and in a totally non-destructive technique. The X-Strata920 is an instant assayer with pin-point accuracy which can analyse the purity of Gold between 8 - 24 Karats. The miniwell base accommodates analysis of small to large samples – from gold links from 0.3 mm diameter to large plated samples up to 160 mm high. This requires minimum user training to confirm Karat content for ensuring correct pricing. It can perform composition and coating thickness analysis for elements from Ti22 to U92. Oxford Instruments’ field proven, microfocus 50 W X-ray tube, and high resolution, sealed Xenon gas filled proportional counter delivers outstanding precision and laser focus, with simple “point and click” function to automatically adjust focal distance (0.5”), improves system reproducibility and minimises user-to-user variability.

The handheld XRF analyser X-MET7000 Series combines the Oxford Instruments’ 40kV X-ray tube, and high performance silicon-drift detector (SDD), providing excellent accuracy and repeatability. With minimal operator training and no requirement for a power source this instrument can be used straight out of the box. This is a rapid, reliable portable analyser which provides accurate and repeatable analysis of precious metal alloys such as jewellery items. The X-MET enables the user to verify products authenticity and value in seconds, with no sample preparation: there is no grinding of sample (no material loss or damage), and no use of chemicals. The X-MET7000 eXpress can provide precious metal analysis in as low as 2 seconds!

Precious metal analysis, such as composition analysis, is required to ensure quality and value of the product. Precious metals such as Gold (Au), Platinum (Pt), Silver (Ag) and Rhodium (Rh) are widely used in the manufacture of jewellery and fashion accessories as the main components or as a thin coating for surface finish. It is essential to analyse the composition and/or plating thickness at the time of manufacture, casting, selling, buying or recycling in order to ensure the quality and value of the final product. This is even more important and critical while testing gold jewellery for the Karat value. Additionally, analysing precious metals for toxic elements such as Lead (Pb) in jewellery means that unsafe items can be removed from the supply chain.

Apart from the jewellery market, Oxford Instruments Industrial Analysis offers products suitable for materials analysis to thickness gauging, incorporating the latest field proven technology, coupled with over 30 years of experience in designing, producing and supporting world class instruments. With leading products and a global sales and service network, Oxford Instruments Industrial Analysis continues to explore innovative ways to deliver instrument solutions for faster and easier measurements and aims to pursue responsible development and deeper understanding of our world through science and technology. Its products, expertise, and ideas address global issues such as energy, environment, security and health.

Principal of X-ray Measurment

High energy photons emitted by a X-ray tube interact with metal. The high energy photon is absorbed by an electron of the atom. This electron is accelerated and forced to leave the atom. The so created hole in the structure of the electron shell is filled up by an electron of higher energy. The difference is energy between the leaving electrons position and the filling up electron may leave the atom as a photon of defined energy or as an electron. In the case of a leaving photon this process is called X-ray fluorescent and the energy of the leaving photon is characteristic for this atom therefore for the element. The electron shells of an atom are called.

K-, L-, M-shell. Filling up a hole in the K-Shell creates, Kradiation (Ka if the filling up electron has is origin in the Lshell, Ka if the filling up electron has is origin in the Mshell). Filling up a hole in the L-shell creates L-radiation and so on. Only K and L radiation is on interest because the energy of K and L radiation is in the region which can be detected with standard detectors. .

This is because up until now, there has been no single meeting-point for the industry. It is this deficit that GemAtlas – the newly establishment web-based business-to-business company moved to fill. www.gematlas.com is a membership-based portal for the diamonds, coloured gems, jewellery, and allied industries. It is the first and only of its kind – a virtual meeting-place where people from around the globe can come together, share knowledge, promote their products and services, and establish business connections and partnerships.

GemAtlas is an India-registered Pvt. Ltd. company, run by experienced e-commerce professionals and expert entrepreneurial minds from the diamonds, gems and jewellery sector. The Company has a proficient staff from various sectors of the industry, as well as information technology specialists and administrative personnel. Speaking about GemAtlas, eminent Jewellery Marketing Consultant Hemant Shah said, “Besides creating a coveted virtual space where industry players can showcase products and services, GemAtlas has the potential to become a “think-tank” that will help create a sustainable future for the diamond, gem and jewellery industry in India and globally.”

How the portal works is that it has over seventy different business categories, and offers the option for registering under multiple categories. There are three types of membership options – “Silver”, “Gold” and “Platinum”. Features offered depend on what level of membership one has opted for. The portal offers members access to a well-organised and easily searchab le database of manufacturers, suppliers, service agencies, consultants, bankers, government agencies, and the like. There are many different service categories on the portal as well. Members can create posts of product and service offerings or requirements, and put them up under service categories they think are most suitable so they go out to relevant audiences. A member will then receive responses from interested parties, and can choose the best alternative to take forward.

Speaking about the Company’s business-model, Mehernosh Printer, well-known consultant for setting up factories, said, “This is exactly what the industry needs. Clients are always asking me for contacts in this area and that. With the advent of the Internet, it became so much easier for manufacturers to find the right machinery and improve processes. Now they can find all the right matches for products and services under one roof, they don’t even need to do extensive online searches. And, this is across the entire value-chain.” The portal also has advertising space available for purchase. This is open for members as well as non-members. This facility presents a valuable opportunity for highly targeted advertising. Already, a lot of industry stalwarts have been connecting with GemAtlas. Some have been contributing informative and thoughtprovoking articles that readers can find on the website. There is also a free registration, for people who just want to receive the newsletter and read the articles, but the free registration only allows limited access on the portal. The site also has a page covering top international trade events across the globe. It has a live update of Forex rates, as well. According to the Company, moving forward, members will be able to advertise products on their own customised web-pages on the portal. GemAtlas also plans to begin hosting seminars, webinars and virtual trade events in the near future.

Speaking about the objectives for the near-future a spokesperson for GemAtlas, said, “It is our endeavour to offer people from the industry every competitive edge – keeping them abreast with the latest happenings, helping them keep track of new technologies and processes, educating them about best practices around the world with regard to HR management, administration, etc, and guiding them towards better business models and corporate governance”.

GemAtlas will function as an interactive “Yellow-Pages” of the Industry – a one-stop referral for all trade contacts. It is poised to realise its dream of building a well-connected community of industry professionals who can reach out to each other and share knowledge, information and ideas, both for their own development and the wider benefit of the industry.

    HRD Antwerp has a long experience in research, examination and grading of diamonds. This has lead to the development of our own analysis tool: a Diamond microscope named D-Scope. This tool has been shaped and refined throughout the years, so that every aspect is optimized for the analysis of diamonds.

    Its main features are:

    Illumination: For the examination of clarity, finish grade and fluorescence.

    Optics: A high quality stereo zoom optical system is used to obtain a clear 3D image through both eyes.

    Manipulation: Move and rotate your diamond, with a maximum flexibility, and a minimal obstruction of the view.

    From the beginning on the illumination has been a corner stone of the instrument. The need to investigate clarity, finishing grade and fluorescence of diamonds has lead to a versatile and flexible lighting solution. New technologies are still pushing the possibilities.

    Heavy demands are placed on the optical system: it has to produce an accurate image to make it possible to study clarity and colour. To gather information on the location of inclusions, it is necessary to have a high depth of view, therefore a stereo-zoom microscope is used. The oculars present images that differ in viewing angle. The mind combines these two images into one, very much like the natural depth perception.

    Manipulation of your diamond with high precision has never been so easy! The gem manipulator works with a vacuum - system to hold the diamond with a minimum of view obstruction. The ingenious system to rotate the diamond allows a flexible and intuitive manipulation. In combination with a D-Stick or an XYstage it covers the whole range of movements.

    ILLUMINATION

    The D - Scope base is equipped with a sophisticated illumination system that consists of a unique halogen or LED darkfield lighting, a TL or LED-daylight and also TL or LED-UV lighting.



    Darkfield illumination

    The dark field illumination was designed to study the inside characteristics of the diamond. A set of mirrors converges the light from all sides into the center of the stone. The smallest inclusions become visible. Yet the light doesn’t produce any disturbing reflections on the outside of the stone. The light comes from the side, so it cannot pass directly into the lens.


    Overhead daylight illumination

    The overhead illumination simulates daylight and therefore offers the best lighting conditions to study clarity, finish grade and even colour. Examining with a 10x loupe can be simulated.



    Overhead fluorescence illumination

    The overhead fluorescence illumination is useful to study the fluorescence of diamonds. The overhead lighting can be tilted to put into optimal position. One can also choose for LED(= Light Emitting Diode) illumination, which replaces the regular halogen and TL-lighting and gives the same examining possibilities. Only LED gives more and a brighter white light to the stone. Ideal for the grader to see at a glance the impurities of the stone being examined.

     

    MANIPULATION

    The most important feature, next to the illumination, is the manipulation of the stone. HRD Antwerp was the first manufacturer in the world who came up with the idea to work with a special vacuum gem-manipulator. The vacuum, created by a pump integrated in the design, is lead through a small tube to a suction pad. This suction pad makes it possible to hold the stone and to move it in all directions without touching it. This allows to study stones from all sides without the view being obstructed.

    There are two different possibilities to manipulate the vacuum gem-manipulator:

    • D-stick: a special designed joystick-like unit


    • XY stage: a more accurate holder to move the stone mm per mm (left/right and up/down)


    For those who prefer the traditional working method, the vacuum gem-manipulator can be replaced by magnetic tweezers. If preferable both systems can be placed together on the base of the microscope.



    OPTICS

    Stereo zoom microscopes provide the ability to see fi ne details in 3D. The optical excellence allows a better, faster and more reliable identification, analysis and measurement. The long working distance permits easy manipulation of the inspected stones. All optics are available in binocular and trinocular format.

    In case of a trinocular type, the third lens hole can be connected to a digital camera, allowing you to make pictures of your stones. All optics are standard equipped with 10x oculars. Other oculars and additional lenses are available on request.





    ERGONOMICS

    The D-Scope was developed for intensive use. So ergonomics and ease of use were very important in the design. The D - Scope is easily adjustable in height and inclination, so the individual user can assume a comfortable position.

    Technical specifications:
    • Power supply: 220V (for countries with 110V a special adaptor is supplied)
    • Frequency: 50 Hz
    • Nominal power consumption: 100 mA
    • Weight: 17 kg
    • Surface of use: 22 x 42 cm (wxd)
    • Height in lowest position: 50 cm
    • CE approved


    ACCESSORIES

    HRD Antwerp graticule kit

    A graticule can be used for:

    • A precise, objective measurement of internal characteristics with the aid of reference circles (1 to 12)


    • Measuring the external dimensions of rounds and all other shapes using the linear scale
    HRD Antwerp combi graticule kit

    The combi graticule combines the use of the HRD Antwerp graticule, for determining the size and depth of inclusions, with those of the graticule for measuring proportions and for measurement angles of inclination.

    Avalight

    By using a special light source, Avalight, one can visualize the surface finish of a facet with very high contrast. Polishing lines can be observed more easily with this light source than with a classical light source. This method makes the grading of stones out of the tang much easier. By putting a facet in reflection with Avalight, the smoothness can be observed instantly.

    Measuring ruler

    This ruler, in combination with the refractive index of diamond, is developed to give exact information at what depth the inclusion is located.



    USB camera

    A low budget camera with adapter to fi t in one of the oculars. Live images and pictures can be obtained. The USB camera can be connected to a PC or laptop, connected to the internet, so that pictures or small video films can be sent over the internet to your customers or suppliers. Other camera systems for trinoculars can be offered on request.

    Transport case/box
    • Pilot case (leather)

    • Trolley (leather)

    • Transport case (plastic, always used for shipments abroad. This to avoid damage to the microscope.)


    Transmitted light

    For examining rough diamonds we have developed a special sorting support with built-in LED illumination. The support is placed, instead of a vacuum gem-manipulator, over the darkfield illumination so both lightings can be used. Rough diamonds are manipulated by hand, but it is also possible to install magnetic tweezers or an XY stage on the sorting support.

    D-SCREEN
    The most compact diamond screening device in the world



    HRD Antwerp has developed the most compact diamond screening device in the world!

    This device identifies natural diamonds (neither synthetic nor HPHT colour enhanced). It can be used for cut diamonds with colour range from D to J.

    Diamond sector threatened by synthetic and treated stones

    Up until the sixties, a colourless or nearly colourless diamond was by definition a natural stone. In the eighties the first synthetic ornamental diamonds appeared on the market. They were made using HPHT synthesis (HPHT = High Pressure High Temperature).

    In 1999, the fi rst reports of commercial HPHT treatment started to emerge. This process gained a great deal of attention, as the technique could turn some brown diamonds into colourless diamonds. It was, after all, the very first technique that could ‘remove’ colour from a diamond.

    In 2001, the American company Apollo Diamond announced its plans to produce synthetic diamonds using CVD techniques (Chemical Vapour Deposition). It also became known that it was possible to ‘remove’ the brownish colour of some CVD synthetic diamonds in order to obtain colourless diamonds by using HPHT treatment. The arrival of these new techniques brought about enormous challenges for scientists and researchers. They embarked upon an intensive search for new techniques that would allow diamond traders, jewellers and consumers to identify the true nature of a diamond: natural, treated or synthetic. These techniques were also to be user-friendly, reliable and economical. Years of research resulted in the launch of a unique device: the ‘D-Screen’.

    The D-Screen is a practical research device developed by HRD Antwerp. It distinguishes stones that are not synthetic and have not been HPHT colour enhanced from stones that are potentially synthetic or may have had their colour improved by means of HPHT.

    What you need to know about colour

    Types of diamonds

    A diamond with a perfect crystal lattice made entirely of carbon would be completely colourless. In reality, however, all diamond crystals contain atomic impurities and structural imperfections. We call these ‘colour centres’ because they are responsible for the colour of a diamond. The most common atomic impurity in a diamond is nitrogen. Based on the presence of this atom in the diamond lattice, one can classify diamonds into two main groups. Type I diamonds contain a higher level of nitrogen, while type II diamonds contain practically no nitrogen.



    What you must know about treatments

    HPHT colour treatment

    General Electric (GE) developed the high pressure (HP) - high temperature (HT) treatment in the mid-nineties with the purpose of changing the colour of ‘lower quality’ (read: light brown) diamonds.

    During this treatment, the stone is heated to temperatures of over 2100°C. To prevent the diamond from being transformed into graphite, this takes place at a very high, stabilising pressure. The brown colour in some types of diamonds (including type Iia) is associated with the presence of plastic deformation or defects in the crystal lattice. HPHT treatment changes these defects in the crystal lattice. Consequently the cause of the colour disappears. The whole process often takes only a few minutes, but the diamond must then be cut to remove the mat, corroded surface to regain its sparkle. The final result of this treatment greatly depends on the initial properties of a diamond and its type. Today a brown, grey or light yellow diamond can be ‘transformed’ into a diamond ranging from intense yellow, to greenish yellow, pink, blue or colourless.

    HPHT synthesis

    The purpose of this technique is to synthetically produce a diamond by replicating the formation conditions of diamonds deep in the earth. By applying a high pressure (HP) and high temperature (HT) to a carbon source, one ‘forges’ a synthetic diamond. Swedish researchers at ASEA were the first ones to produce a diamond by using this method in 1953. They were soon followed by General Electric and De Beers. Since the seventies, gem quality diamonds have been produced by HPHT synthesis. Today, they are sold for about 30% of a natural diamond’s price. By keeping the conditions stable for a longer time, one can ‘grow’ a rough diamond up to 2 to 3 carats in just a few days. The majority of these stones are coloured bright yellow to orange due to the presence of nitrogen atoms in the crystal lattice. They are type Ib diamonds. It is also possible to grow colourless (read: nitrogen-free) diamonds, but the technical problems involved remain sizeable and such stones are practically absent from the diamond market.

    CVD synthesis

    Chemical Vapour Deposition is the process through which a diamond is produced from a (carbonaceous) gas.

    The principle was already known in the nineteen thirties, but it took until the beginning of this century before one succeeded in growing larger single diamond crystals instead of polycrystalline material. The gas (methane is usually used) is heated to a very high temperature. Atom compounds are then broken down. Then, carbon atoms can be ‘precipitated’ onto a surface. Under the right conditions, a single crystal is formed that becomes thicker layer by layer. A typical speed for a good quality diamond is half a millimetre a day. CVD synthetic diamonds are - considering the complexity of the process - usually light brown, making them relatively unattractive to the average diamond trader. However, this brown colour can often be removed using HPHT treatment. As scientists are continuously defying the limits of technology, colourless diamonds are expected to become available in the future.







    First, make sure that the stone is a diamond, cut (one facet is enough), colour D to J, weighing between 0.20 and 10 carat.

    Then, place the diamond to be examined table downwards on the detector. Close the device. After a few seconds, the result appears on one of the indicators:

    Power supply: 9 V DC, 250 mA

    Adaptor input: 110-230 V, 50/60 Hz
