Gemesis Stakes Claim to World’s Largest Lab-Created Diamond

Gemesis Diamond Co. debuted what it’s calling the world’s largest, whitest lab-created diamond weighing 1.29 cts.

The emerald-cut diamond, certified by the International Gemological Institute, is classified as the purest Type IIa, E color, with VVS2 clarity.

 

The mega manmade rock retails for $7,633.64. 

“This is a significant milestone,” Gemesis director of marketing Martin DeRoy said in a statement. “Gemesis is proud to offer lab-created diamonds that possess the same exceptional quality, color and clarity as mined diamonds. We look forward to continuing to produce high colors in larger sizes, with increased regularity in the near future.”

D.NEA Diamonds claimed to have the largest, whitest, cleanest lab-grown diamond in March after getting a 1.07 ct. synthetic diamond certified by AGS. That stone was selling at time for $5,767.
