Rare Pink Diamond Ring Expected to Fetch $9M at Phillips Geneva Auction
A rare fancy vivid purplish-pink diamond ring is expected to lead Phillips’ Geneva Jewels Auction: V on November 10, with an estimated value of around $9 million, the auction house announced last week.
The centerpiece of the ring is a 6.95-carat, VVS2-clarity, type IIa pink diamond, flanked by two triangular white diamonds. Its vivid color and exceptional clarity place it among the most coveted stones in the world of high jewelry.
The Geneva auction will also feature a selection of prestigious pieces, including jewels from the Vanderbilt family collection, and signature creations by top luxury houses such as Van Cleef & Arpels, Cartier, Bulgari, and Graff.
Ahead of the sale, Phillips will tour highlights from the collection across major cities including New York, Singapore, Taipei, and London, before presenting the full auction in Geneva.
This ring features a step-cut, 18.09-carat Kashmir sapphire with diamond shoulders. It has an upper estimate of CHF 2.2 million ($2.8 million).
A pair of earrings consisting of brilliant-cut, D-color, VVS1-clarity diamond studs weighing 8.28 and 8 carats will go on the block for up to CHF 680,000 ($850,000).
Phillips will offer this ring, bearing an old-cut, 10.08-carat, light-brown-pink, type IIa Golconda diamond. It’s expected to fetch up to CHF 520,000 ($650,000).
Schlumberger created this necklace in the 1950s. The piece, which includes diamonds, rubies, and sapphires, has a high price of CHF 400,000 ($500,000).
A pair of Graff earrings with octagonal step-cut, fancy-yellow diamond center stones weighing 21.38 and 20.33 carats surrounded by diamonds is estimated at up to CHF 400,000 ($500,000).
This diamond sautoir that Van Cleef & Arpels made in the 1920s has a step-cut diamond weighing 10.79 carats. The lot carries an upper price of CHF 400,000 ($500,000).
A ring with a 4.95-carat Burmese ruby and diamonds has a top estimate of CHF 320,000 ($400,000).
A convertible piece, this lot can be worn as a tiara or a necklace. Created in the second half of the 19th century, it has sapphires and diamonds, and carries a high estimate of CHF 320,000 ($400,000).
Bearing a 20.08-carat Paraiba tourmaline center stone in a diamond surround, this ring is anticipated to go for up to CHF 280,000 ($350,000).

Big, Slightly Tinted Diamonds: Object Of Desire In The US Market
Buyers Of 2.5-Carat and Up Pieces Are Increasingly Choosing Stones With J Color Or Lower, Sometimes Much Lower On The Color Scale
Big, slightly tinted diamonds are suddenly the object of desire in the US — and the industry is asking why.
Buyers of 2.5-carat and up pieces are increasingly choosing stones with J color or lower, sometimes much lower on the color scale, say retailers and traders. That shift signals more than a fashion tweak: it reflects how affluent shoppers now want their diamonds to read as “natural” at a glance.
Lab-grown gems typically come in the brightest, clearest grades, so a warmly hued, imperfect-looking stone has become a visible badge of authenticity — a deliberate antique vibe in a polished world where synthetics dominate. No surprise: The Knot reports that 61% of U.S. couples now pick lab-grown rings.
A report explores who’s buying these larger, lower-color stones, how cultural moments and celebrities — think Taylor Swift — helped fuel the taste for them, and why antique cuts seem particularly suited to carrying color. The piece also ties this appetite to broader marketing narratives, including De Beers’ push for so-called “Desert diamonds.”
It’s not all doom and gloom for mined diamonds. Larger sizes — especially 2 carats and above and long fancy shapes — have held up better than smaller goods over the past year. The report isolates this rising niche and asks the key question: can these warm-toned showstoppers withstand the continued rise of lab-grown competition?
