A Rare 15-Carat Yellow Diamond Ring Could Fetch $1.2 Million at Auction This Spring

Phillips wants to help brighten up your jewelry box.

The auction house is offering a dazzling selection of colored diamonds and gemstones at its Hong Kong Jewels sale on March 28. Such rarities continue to be go-to investments and are thus in high demand. The spring sale will include some of the finest Burmese rubies, Colombian emeralds, red spinels, and Paraiba tourmalines, according to Phillips. Vintage signed pieces by names like Van Cleef & Arpels, Cartier, and Bulgari will also be up for grabs. The star of the show, however, is a 15.51-carat fancy vivid yellow diamond (pictured top).

Positioned between two white diamonds on top of a ring, the mesmerizing stone has a round brilliant-cut style that is uncommon with colored diamonds due to the high waste of raw materials it causes. As such, this particular piece is considered extremely rare. So much so that it is estimated to hammer down for between $950,000 to $1.25 million at the auction.

The sale will spotlight two other colored gems that are set on rings, too, including a 1.38-carat fancy vivid purplish pink diamond (estimate: $425,000 to $560,000) and a 2.65-carat fancy intense orangy pink diamond (estimate: $300,000 to $400,000).

Other brightly hued highlights of the auction include a breathtaking bracelet adorned with 24.59 carats of Burmese rubies and diamonds (estimate: $230,000 to $300,000) and a pair of Harry Winston earrings featuring 10.05 carats of Colombian emeralds (estimate: $120,000 to $180,000). In addition, a striking Mozambican Paraiba Tourmaline and a luxe 10.32-carat Burmese Res Spinel will go under the gavel.

As for signed jewelry, collectors can bid on an eye-catching Van Cleef & Arpels turquoise and diamond necklace circa 1985 (estimate: $110,000 to $150,000) and an Art Deco-style Burmese ruby and diamond bracelet by Cartier that feels straight out of a Bridgerton scene (estimate: $40,000 to $52,000).

Highlights from the auction will be exhibited in Singapore from March 8 to 9, Taipei from March 16 to 17, and Hong Kong from March 20 to 28. You can visit the Phillips website to peruse the full catalog.
