IGI Analyzes Record 150 Carat Rough Lab Grown Diamond

(PRESS RELEASE) NEW YORK — The International Gemological Institute (IGI), the world’s largest independent gemological laboratory, recently analyzed the heaviest known rough diamond crystal ever to be grown in a laboratory.

Produced by biotechnology company Meylor Global, the record setting blue crystal weighs 150.42 carats and measures 28.55 x 28.25 x 22.53 mm. A second gray crystal weighing 141.58 carats and measuring 28.90 x 28.50 x 20.75 mm, was also analyzed by the institute.

These crystals were produced using the HPHT process, which replicates and accelerates natural growth. Both of them surpass the previous known record of 115 carats established in September, 2020, also by Meylor Global.

“The acceleration of technology in the lab grown diamond sector is significant,” said IGI Senior Director of Education, John Pollard. “In addition to record-setting weights, they’re type IIb crystals, a semiconducting category associated with diamond-based electronics. At IGI we’re seeing new benchmarks from the world’s most advanced producers in jewelry applications and beyond.”

When the Kids Have Their Own Careers, Wilkerson Can Help You to Retire

Alex and Gladys Rysman are the third generation to run Romm Jewelers in Brockton, Mass. And after many decades of service to the industry and their community, it was time to close the store and take advantage of some downtime. With three grown children who each had their own careers outside of the industry, they decided to call Wilkerson. Then, the Rysmans did what every jeweler should do: They called other retailers and asked about their own Wilkerson experience. “They all told us what a great experience it was and that’s what made us go with Wilkerson.” says Gladys Rysman. The results? Alex Rysman says he was impressed. “We exceeded whatever I expected to do by a large margin.”
