Sotheby’s Withdraws Rare 10-Carat Pink Diamond from Geneva High Jewelry Auction
The $20 million ‘Glowing Rose’ was expected to lead the sale but was removed after discussions with the consignor.
Sotheby’s has withdrawn a rare 10.08-carat fancy-vivid-pink diamond from its High Jewelry auction in Geneva, where it was estimated to fetch around $20 million. The Glowing Rose—a cushion brilliant-cut pink diamond set in a ring—was slated to be the star lot of the November 12 sale but never reached the auction block. The company did not disclose the reason for the withdrawal.
“The Glowing Rose is an absolutely beautiful pink diamond… however, following discussions with the consignor, the lot was withdrawn prior to the sale,” a Sotheby’s spokesperson told. The stone is notable as only the third cushion-cut vivid-pink diamond to appear at auction in the past decade and was showcased in Singapore and Taipei last month in a presentation mount by British jeweler Boodles.
Despite the withdrawal, the High Jewelry sale achieved CHF 29.8 million ($37 million), led by a 4.50-carat fancy-vivid-blue, internally flawless diamond that sold for CHF 4.8 million ($6 million). The event ran parallel to Sotheby’s Royal & Noble Jewels auction in Geneva.

Motorsport Meets High Jewellery: Hannah St John Turns Heads with ‘La Velocita’ Diamond Necklace at F1 Event
A 25-carat, 1,800-diamond Masterpiece Inspired by Formula 1 circuits Takes Centre Stage at the Glamour on the Grid ahead of the Australian Grand Prix
At the glamorous lead-up to the Australian Grand Prix, Hannah St John, partner of Liam Lawson, made a striking statement at the Glamour on the Grid event with a one-of-a-kind diamond necklace that seamlessly blended motorsport and haute jewellery.
Titled “La Velocit” (The Speed), the necklace was crafted by Australian atelier Martin Rogers Jewellery. The extraordinary piece features approximately 1,800 diamonds totalling 25 carats, intricately arranged to trace the outlines of iconic Formula 1 circuits from the global racing calendar.



A true testament to craftsmanship, the necklace required an estimated 250–300 hours of meticulous handwork, including weeks dedicated solely to precision diamond setting. Valued at around AUD $500,000 (approximately $350,000 USD), the piece stands as a bold fusion of speed, design, and luxury artistry.
Blurring the lines between engineering inspiration and fine jewellery, “La Velocità” captured attention across the paddock, proving that Formula 1’s influence extends far beyond the track.
