Diamonds, Colored Gems Steal Show at Heritage Auction

May 11, 2023  |  Anthony DeMarco

A platinum ring featuring an emerald-cut, 5.02-carat diamond sold for $225,000 at Heritage Auctions’ Spring Fine Jewelry Signature sale on Monday, surpassing its high estimate of $175,000.

The E-color, VVS2-clarity gem was the top lot at the auction in Dallas, Texas, the company said Monday. Overall, the sale of more than 1,000 lots achieved $5.1 million.

A 13.87-carat Madagascar sapphire (below) was the number-two item at the sale, fetching $200,000, more than five times its low estimate.

The blue sapphire was just one of several high-performing pieces bearing colored gemstones, nearly all from the single-owner Edgehill collection, the auction house said. Paraiba tourmalines from the estate of a Colorado collector and several unmounted diamonds also performed well.

Meanwhile, an 8.56-carat diamond that was billed as the top lot prior to the auction, with a $250,000 upper estimate, failed to sell. The cushion-shaped, H-color, VVS1-clarity gem remains on the auction house’s website with a $250,000 asking price.

Other lots included:

A round brilliant, 5.14-carat diamond with F color and VS1 clarity, which sold for $162,500.

An oval-shaped, 8.05-carat Mozambique ruby, which brought in $137,500.

A loose emerald-shaped, 9.03-carat diamond with K color and VS1 clarity, which fetched $131,250.

The remaining top lots were loose fancy-colored gems. They were:

A 33.56-carat Ceylon Sapphire with an octagonal step shape, which achieved $125,000 (below).

A rectangular cushion-shaped, 11.88-carat ruby, which sold for $109,375.

A pear-shaped, 2.58-carat Paraiba tourmaline that sold for $106,250.

An oval-shaped, 2.64-carat Paraiba tourmaline, which went for $103,125 (below).

An oval-shaped, 40.02-carat Colombian emerald that realized $100,000.
