The International Gemological Institute (IGI) has graded a 30.18-carat lab-grown that it claims is the world’s largest polished synthetic diamond.

Mumbai-based lab-grown company Ethereal Green Diamond created the emerald-cut, H-color, VS2-clarity diamond, named Pride of India, IGI said last week. The stone was made using chemical vapor deposition (CVD).

The polished diamond was fashioned from a rough that took approximately four weeks to grow, IGI noted. Ethereal Green Diamond plans to continue to work on creating record-setting lab-grown diamonds, the company’s managing director, Hirav Anil, told IGI.

The lab-grown maker planned to exhibit the diamond at the JCK Las Vegas show, in a booth just near the display of the previous record holder — a marquise step-cut, 27.27-carat synthetic diamond created by Greenlab — IGI explained. That stone just nabbed the record last month.
