The International Gemological Institute (IGI), the world’s largest independent gemological laboratory, has analyzed and graded a 30.18 carat emerald cut laboratory grown diamond, the world’s largest to date. Produced by Ethereal Green Diamond, LLP the 30.18 ct “Pride of India” is the first polished lab grown diamond to exceed 30 cts. This breakthrough comes on the heels of record-setting 27.27 and 20.24 ct stones, analyzed and graded by IGI last month. This week’s JCK Las Vegas attendees can see all of these gemstones in person: The 30 carat “Pride of India” will be on display with Ethereal Green Diamond at booth #8135, and the 27 and 20 carat creations will be exhibited by Greenlab Diamonds at booth #8131.
