IGI Certifies Largest Lab Grown Diamond to Date: 35.00 carats

Maitri to display gemstone at JCK Las Vegas

Antwerp, Belgium (May 29, 2023) – The International Gemological Institute (IGI), the world’s largest independent gemological laboratory, has analyzed and graded a 35.00 carat laboratory grown diamond, the largest to date.

Produced by Maitri Lab Grown Diamonds (Maitri), the new record holder was polished into an emerald cut measuring 23.37 x 15.24 x 9.06 millimeters. The Type IIa rough crystal from which it was fashioned was grown using the Chemical Vapor Deposition (CVD) process. Maitri will have the gemstone on display at JCK Las Vegas, June 2-5, booth #8123.

Maitri commented: “We are thrilled to unveil this remarkable 35 carat lab grown diamond, an achievement which follows extensive research and development efforts, reflecting our dedication to excellence. Having this milestone certified by IGI strengthens its authenticity and pedigree, reinforcing our position of leadership in the industry and showcasing the immense potential of lab grown diamonds.”

Lab grown diamonds have revitalized the jewelry industry, offering consumers an authentic, affordable alternative to mined diamonds. According to statistician Edahn Golan, loose lab-grown diamond unit sales held a share of 13.7% in 2020. Since then, their share has nearly tripled, to 33.8% in 2022.

“IGI is proud to certify new benchmarks like this exceptional lab grown diamond from Maitri,” said Avi Levy, President of IGI North America. “The increasing sophistication and quality of achievements we’re seeing from the top producers are remarkable. These breakthroughs also underscore how vital screening, grading and disclosure are, in the interest of continued confidence and growth for our industry.”

IGI will be providing onsite diamond screening and grading services at JCK Las Vegas, booth #8055. Attendees are invited to join IGI for two JCK Talks sessions: “Lab Grown Diamond 101 (and beyond)” on Thursday, June 1 from 5:00-5:45 pm in room 101, Expo Level I, and “Lab Grown Diamond Updates” on Saturday, June 3, from 10:00-10:45 am, Expo Level II Showcase Stage.
