Washington, D.C.--A lab-grown diamond company announced Monday that it is now producing high-quality 2-carat diamonds and expects to be growing 3-carat stones by early 2015. 

The International Gemological Institute has certified both a round brilliant, 2.03-carat E, VS2 and a 2.21-carat princess-cut E, SI2 stone from Washington Diamonds Corp., the company said.

These are not the largest lab-grown diamonds ever produced; Pure Grown Diamonds (formerly Gemesis) claims to hold that honor following its production of a 3-carat diamond this summer. But that stone has a lower color, K, and clarity, SI1, than the new 2-carat diamonds Washington Diamonds said it is producing. 

 “Our production of D and E color diamonds with excellent clarity and exceptional size is introducing a new era for lab grown stones,” said Washington Diamonds Founder and Chairman Clive Hill.

Hill, the former CEO of U.K. jewelry chain Fraser Hart, launched Washington Diamonds in 2008 to serve the jewelry and gemstone markets. The firm is also exploring high-tech and industrial applications for its diamonds.
