6.21-Carat Oval Pink Diamond Could Fetch $15MM at Phillips' Geneva Auction

Phillips is estimating that a magnificent 6.21-carat Fancy Vivid Pink diamond ring could fetch as much as $15 million as the star lot of its "Geneva Jewels Auction: TWO" on May 13.

Other baubles expected to turn heads at Hotel President Geneva include a 280.84-carat Colombian emerald and a super-rare 1.56-carat Fancy Red diamond.

In all, the meticulously curated sale of just over 100 lots will showcase signed jewels from illustrious houses such as Cartier, JAR, Sterlé, Suzanne Belperron, and Van Cleef & Arpels.

The property of an "important private collector," the 6.21-carat pink diamond boasts a VS1 clarity and a Type IIa classification reserved for diamonds of exceptional purity and transparency. The gem's Fancy Vivid rating sits at the top of the diamond color grading scale. The oval diamond is set in a ring between two kite-shaped diamonds.

The auction house set the estimated sales range at $10.5 million to $15 million.

Pink diamonds are in high demand and short supply since the November 2020 closure of Rio Tinto’s Argyle mine in Australia, which had been the world’s primary source of high-quality pink diamonds.

The “CTF Pink Star” still holds the record for any gem sold at auction. The 59.6-carat pink diamond sold at Sotheby’s Hong Kong for $71.2 million in 2017.

Other auction highlights include the following:

An octagonal step-cut emerald weighing 280.84 carats, "The Amazon Queen" is expected to sell in the range of $1.5 million to $2.6 million. The gem measures 40mm x 35mm (about 1.5 inches square) and was sourced in Colombia.

"The Argyle Phoenix" is a brilliant-cut Fancy Red natural color diamond sourced from the now-depleted Argyle mine. Red is said to be the rarest diamond color in the world. "The Argyle Phoenix" is expected to fetch between $1 million and $1.5 million.

Set with pear-shaped Fancy Intense Yellow and Fancy Yellow diamonds weighing from 0.44 carats to 11.28 carats, and an oval Fancy Intense Yellow diamond weighing 5.44 carats, this Harry Winston-designed necklace is expected to sell in the range of $300,000 to $500,000.

A ring featuring a cut-cornered Fancy Intense Green diamond weighing 2.26 carats framed by circular-cut pink sapphires should yield from $260,000 to $380,000 based on Phillips' pre-sale estimate. The green diamond boasts a clarity of VS1.

Top lots from Geneva Jewels Auction: TWO will be traversing the continents before returning to Geneva for the auction. Tour stops will include New York, London, Taipei and Singapore before returning to Hotel President Geneva from May 8 until the sale on May 13.
