 The International Gemological Institute (IGI) recently graded a 116-carat, black synthetic diamond that ranks as the largest lab-grown diamond of its color.

The 115.65-carat, type IIb stone was produced by UK-based Meylor Global using High Pressure-High Temperature (HPHT), and was accompanied by a second black lab-grown diamond weighing 109.58 carats, IGI said Wednesday.

“The innovative approach in physical chemistry of diamond growth, combined with sophisticated technological methods and advanced high-pressure equipment, allowed us to obtain record-breaking extra-large diamond single crystals, having in mind the idea of getting the biggest possible diamond plate,” said Meylor CEO Yuliya Kusher.

Meylor grew the diamonds as part of its “World’s Largest Black Diamonds Project,” which it began at the beginning of the year. However, it intends to try for a larger one in the future. The larger stone holds the Guinness World Record for its category, IGI reported.

“The significant milestone of [over 100 carats] in diamond size was achieved by our company in a very short time, and the next even more promising target of [over 200 carats] is right now under deep scientific investigation,” Kusher added.
