WD Lab Grown Diamonds, leading U.S.-based producer of Chemical Vapor Deposition (CVD) laboratory grown diamonds, has entered into a patent sublicensing agreement with Ethereal Green Diamonds LLP (“EGDL”) and its affiliate The Diamond Library. This agreement is an expansion on WD’s sublicensing program, announced late 2020, which to date includes ALTR (India) Private Limited and ALTR, Inc. and Evolution Diamond. EGDL is now likewise permitted to license and distribute CVD lab grown diamonds in the United States, Canada, Mexico and all other global territories where the patents are applicable.

"We are pleased to welcome EGDL as new sublicensees of WD's industry-leading diamond growth technology," said Sue Rechner, Chief Executive Officer of WD Lab Grown Diamonds. “Our commitment to ethical business practices and sustainability informs all that we do at WD, and this partnership reflects EGDL’s shared dedication to corporate responsibility, consumer-centricity and transparency.”

EGDL is a prominent manufacturer and distributor of laboratory grown diamonds, headquartered in Mumbai, India with offices in New York. “The EGDL team is pleased to join the esteemed ranks of WD Lab Grown Diamond patent portfolio sublicensees,” said Hirav Virani, Director at Ethereal Green Diamonds, LLP. “This was a logical next step for us, as we share in WD’s mission to increase consumer access to high-quality laboratory grown diamonds. We proudly align with their commitment to integrity, ethics and responsible business practices in the diamond industry.

This sublicensing agreement incorporates WD's full patent portfolio, and importantly those developed through the Carnegie Institution of Washington. The first relevant Carnegie patent (6,858,078, February 2005) covers CVD diamond growth using microwave-plasma; the second (RE41,189, April 2010) reflects a high-pressure, high- temperature annealing process that improves a diamond's visual qualities. All diamonds produced through WD's patented and sublicensed technology are Type IIA, recognized as the highest quality and representative of just 1-2% of diamonds on earth.

With the expansion of their sublicensing program, WD reinforces its mission to increase consumer access to responsibly-created laboratory grown diamonds.
