IGI analyzes record 150 carat rough lab grown diamond

(NEW YORK) – The International Gemological Institute (IGI) has reported recently analyzing 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.”
