Clarity

Diamonds grown using CVD Diamond Technology have been examined by noted experts in the United States, Europe and Australia and the leading grading agencies (GIA, EGL, IGI) announced that as of January 2007 they would begin offering certification for cultured diamonds. In 2008, the GIA noted that the recent diamond samples showed “significant improvements in size, color and clarity” over the first (2004) sample, and that cultured diamonds grown using CVD Diamond Technology are “comparable in color and clarity” to mined diamonds.

  • Fancy-colored “pink” cultured diamonds grown using CVD Diamond Technology have likewise been well received. Experts in Australia and the United States intimately familiar with the top quality pink diamonds mined from the Argyle mine in Western Australia all concur that the pink stones grown using CVD Diamond Technology are extremely attractive diamond gemstones.
  • The GIA confirmed these impressions when it published findings from its recent analysis of nineteen (19) pink diamond gemstones grown using CVD Diamond Technology. These diamonds graded colors of “fancy vivid purplish pink,” “fancy deep purplish pink,” “fancy intense purplish pink,” “fancy deep pink,” and “fancy intense pink” with clarities largely of VS and VVS (two stones graded SI).
  • The GIA stated the pink diamonds grown using CVD Diamond Technology are “comparable to top quality natural pink diamonds” and “offer a potential new source of attractive gem quality material in the marketplace.”

Due to their rarity, high-quality pink diamonds attract a select clientele and typically sell for significant multiples to comparable white diamonds.

  • Ninety percent (90%) of the available pink diamonds are produced from the Rio Tinto, plc owned Argyle mine in Western Australia.
  • Each year Rio Tinto offers less than 100 finished carats (typically 60-65 carats) of its best pink diamonds (the “Argyle Signature Stones”) for sale through the annual Pink Diamond Tender.
  • These best pink diamonds are known to fetch prices of $100,000-$1,000,000 per carat.
