Las Vegas— The JCK Show 2024 in Las Vegas featured a groundbreaking display by the International Gemological Institute (IGI), which showcased and graded the world’s largest lab-grown diamond, a 75.33 carat square-emerald cut stone. Alongside it was the distinctive 30.69 carat ring-shaped diamond, formed from a single crystal grown using Chemical Vapor Deposition (CVD). Named the “Celebration of India” and “Infinity Ring” respectively, these milestones were presented by Ethereal Green Diamond LLP in collaboration with RockRush (SoHo, New York) at booth #8135.
The 75.33 ct diamond was graded by IGI as a type IIa with excellent polish and symmetry. Initially grown to a rough stone weighing 190 carats over approximately 270 days, it took around 30 days for cutting and polishing. Hirav Virani, Director at Ethereal Green, expressed, “At Ethereal Green, we are constantly innovating, adopting new technology, and setting benchmarks. It gives me immense pleasure to showcase ‘Celebration of India,’ which not only set a new milestone at 75 ct but also commemorates sovereign India’s remarkable achievements spanning over 75 years of independence.”
In the previous year, the honorable Prime Minister of India, Narendra Modi, presented an IGI-certified 7.5 ct lab-grown diamond to the First Lady of the United States, Dr. Jill Biden, as part of the celebrations marking India’s 75th Independence anniversary.
