5.01 carat Type IIa diamond sold by Heritage for 175,000 dollars

A 5.01-carat flawless, colorless Type IIa diamond mounted on an 18k gold ring fetched an impressive $175,000 at Heritage’s Spring Fine Jewelry Signature® Auction held on Monday. Type IIa diamonds, characterized as the most chemically pure, are exceptionally rare, constituting less than 2 percent of all diamonds, rendering this gem among the scarcest on Earth. Prior to the auction, Jill Burgum, Heritage’s Executive Director of Fine Jewelry, remarked, “This diamond epitomizes perfection—boasting superior color, clarity, and a Type IIa classification. It’s a pinnacle example.”

Initially valued at $50,000, the platinum-topped 18k gold bracelet, adorned with approximately 74.00 carats of oval and cushion-shaped sapphires, ultimately fetched $162,500—nearly $150,000 beyond its high pre-auction estimate. Another eye-catching bracelet, featuring a spectrum of colored diamonds, surpassed expectations, realizing a final bid of $150,000.
