IGI Certifies Guinness World Record Diamond Ring

Institute analyzes wearable jewelry with 12,638 diamonds

The International Gemological Institute (IGI) documented another notable achievement with its certification of a Guinness World Record holder. Created by Renani Jewels and Jewelry Designer Harshit Bansal, the historic ring totals 12,638 diamonds – smashing previous records by more than 4,800 stones.

Floral-inspired, “The Marigold – The Ring of Prosperity” totals 38.08 carats and weighs 5.8 ounces. Certified by IGI India under the leadership of Managing Director Tehmasp Printer, the collection of breathtaking round brilliant diamonds used in the piece are all E-F color and VVS clarity, placing them in the elite “collection category” of colorless, nearly-flawless natural diamonds.

“I am proud of the Institute for accomplishing this landmark certification, making it the fifth jewelry piece certified by IGI to enter the Guinness book of records,” said IGI CEO Roland Lorie. “We are excited about the prospect to grade and certify more history-making jewels in the years to come.”

The ring began to take shape in 2018 and was completed in February 2020. A departure from common symmetry, every petal in the piece is created with a unique design: no two petals are identical, giving the eight-layered piece a perfect blend of organic symmetry, style and alignment.

Harshit developed the concept of the ring in Surat, the diamond hub of India, after receiving his BBA and MBA from SRM University. While opening his first store, he read about the 2018 Guinness World Record ring with 6,690 diamonds and became determined to surpass it. He always had a target of 10,000 diamonds, considering and discarding many ideas before settling on The Marigold.

“I was trying to think about designs for a long time and eventually found it in my garden. A marigold flower caught my eye and I put it in-between my fingers to see how it would look. It was then that I decided this was my inspiration,” explained Harshit.
