Type IIa diamonds are the most chemically pure diamonds known to exist. They can be found in gray, light brown, light yellow or light pink, but the most sought-after are colorless.
"Colorless Type IIa diamonds are the standard for those who desire perfection in their stones," said Jill Burgum, Senior Director of Fine Jewelry at Heritage Auctions. "They are extremely rare – only 1-2% of earth-grown diamonds qualify as Type IIa. The lack of any kind of internal impurities in these colorless stones is extraordinary. To offer three exceptionally rare Type IIa diamonds in one auction is beyond exciting."
A Diamond, Platinum Ring, GIA Type IIa (estimate: $100,000-150,000) features a heart-shaped diamond weighing 3.55 carats between pear-shaped diamonds weighing a total of approximately 0.50 carat, set in platinum.
Also offered is a breathtaking Unmounted Diamond, GIA Type IIa (estimate: $60,000-80,000), a marquise-shaped diamond weighing 3.34 carats.
A third remarkable jewel, Diamond, Platinum Ring (GIA Type IIa) showcases a D/Internally Flawless pear-shaped diamond weighing 3.01 carats, balanced by triangular-shaped diamonds with a total weight of approximately 0.80 carat, set in platinum (estimate: $60,000-70,000).
