35-Carat Lab-Grown Diamond Going on Display in Vegas
Created by Maitri Lab-Grown Diamonds and graded by IGI, it’s slightly bigger than the record-setting lab-grown diamond GIA just examined.

Maitri Lab-Grown Diamonds created the emerald-cut, Type IIa stone using the chemical vapor deposition (CVD) process. The company, which has offices in Surat, India, and New York, said it took approximately 1,800 hours (75 days) to grow the diamond.
The International Gemological Institute graded it as H color, SI1 clarity.
IGI said the 35-carat stone is the largest polished lab-grown diamond to date, topping the 34.59-carat diamond the Gemological Institute of America detailed in a research note published in early May.
“IGI is proud to certify new benchmarks like this exceptional lab-grown diamond from Maitri,” IGI North America President Avi Levy said. “The increasing sophistication and quality of achievements we’re seeing from the top producers are remarkable.”
The diamond will be on display at Maitri’s booth at JCK, 8123.
The 2023 JCK show in Las Vegas kicks off Friday.
At the jewelry trade show, IGI will be participating in two “JCK Talks” education sessions on lab-grown diamonds.
“Lab-Grown 101” with Levy and IGI Senior Director of Education John Pollard is scheduled for Thursday from 5-5:45 p.m. in the Venetian Expo, Level 1.
“Lab-Grown Diamond Updates” is scheduled for Saturday from 10-10:45 a.m. on the Showcase Stage, Venetian Expo, Level 2.
Levy will be joined by JCK News Director Rob Bates, industry analyst Edahn Golan, and Joanna Park-Tonks, president of the International Grown Diamond Association (IGDA).
IGI also will be providing onsite diamond screening and grading services at JCK, booth 8055, and hosting daily happy hours starting at 4 p.m. at booth 12037 in the Design Lounge.
JCK Las Vegas 2023 continues through Monday.
