Washington, D.C. Company Grows 6-Carat Diamond
WD Lab Grown Diamonds says it’s the largest round diamond ever produced using CVD technology.
This 6-carat round diamond was created using the chemical vapor deposition (CVD) process.
Washington--A lab-grown diamond company based in the United States says it just grew a 6-carat diamond using the chemical vapor deposition (CVD) process.
WD Lab Grown Diamonds, whose facility is located just outside Washington D.C., recently created the 6-carat round stones, which it claims is the largest round diamond on record to be produced using CVD technology.
Back in 2016, the Gemological Institute examined a 5.19-carat cushion modified brilliant grown using the CVD process, noting that, “Chemical vapor deposition (CVD) technology has accelerated over the last several years, and the rapidly improving techniques have produced large, high-quality near-colorless and colorless synthetic diamonds.”
Around that same time, the lab also examined a 10.08-carat man-made diamond, though that stone was created using the high-pressure, high-temperature (HPHT) process and was blue in color, not white.
WD Diamonds said it took a few months to grow the 6-carat round, which sold less than a month after it began showing it to buyers.
The company, which creates lab-grown diamonds both for the diamond trade and for industrial and scientific purposes, said it is now concentrating on producing diamonds above 6 carats to sell to its retailers.
Clive Hill, founder and chairman at WD Lab Grown Diamonds, said, “Our patented technology and industry-leading engineers consistently provide top-quality results that only the latest innovation can offer.”
WD Diamonds was founded in 2008 and is the exclusive licensee of the single-crystal CVD diamond growth technology developed by The Carnegie Institution of Washington.
