WD Lab Grown Diamonds Announces New CVD Patent Sublicensing Partner

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.
