Sotheby’s Geneva is set to unveil another of nature’s rarest treasures: The Glowing Rose, a magnificent 10.08-carat cushion brilliant-cut Fancy Vivid Pink diamond of exceptional quality. It is only the third vivid pink cushion-cut diamond over 10 carats to come to market in the past decade.
The Glowing Rose, a 10.08-carat Fancy Vivid Pink diamond, remarkable for its exceptional colour and clarity, will be headlining Sotheby’s High Jewellery Sale in Geneva on 12th November 2025. This extraordinary gem is only the third vivid pink cushion-cut diamond over 10 carats to appear at auction in the past decade. This natural wonder is expected to achieve around $20 million, marking it as one of the most anticipated highlights of the upcoming sale.
“Building on the remarkable success of The Mediterranean Blue, we are thrilled to present another extraordinary fancy coloured diamond, this time an exceptional pink diamond, just over 10 carats in weight. With the current high global demand for rare, coloured diamonds, the chance to offer The Glowing Rose, a superb and extremely rare, coloured diamond, makes this auction moment truly exciting,” noted Jessica Wyndham, Head of High Jewellery, Sotheby’s Geneva.
Named after its luminous and pure pink colour – an extremely rare occurrence, as most pink diamonds display secondary modifying hues, this dazzling diamond will be sold on 12 November as part of Sotheby’s High Jewelry Sale to be held at the Mandarin Oriental in Geneva with an estimate in the region of $20 million.
Ahead of the auction, The Glowing Rose was exhibited in Singapore and Taipei in October, displayed in a presentation mount specially designed by British heritage jeweller Boodles, one of the world’s foremost purveyors of pink diamonds.
The platinum band features baguette and brilliant-cut white diamonds to create a contrast to the spectacular pink hue of the diamond. A subtle chevron of pinks at the end of the row of whites adds a finishing touch. By setting the pink diamonds in Single Mine Origin pink gold further emphasises the contrast between the platinum and the pink.
“Boodles is delighted to partner with Sotheby’s in bringing our distinctive design and exquisite setting to this most spectacular and important of vivid pink diamonds. This is a high watermark in a longstanding relationship we have both enjoyed over very many years,” Jody Wainwright, Managing Director, Boodles Ltd.
With cushion-shaped diamonds benefiting from global peak attention following the recent unveiling of Taylor Swift’s engagement ring, The Glowing Rose, with its cushion shape, has everything to appeal to the most discerning of diamond collectors: a wonderfully saturated colour, very high clarity and, at just over 10 carats, a fabulously rare size for a pink diamond of this quality. Often chosen for its ability to best showcase the diamond’s colour saturation and brilliance, the cushion cut is especially admired in pink diamonds, as its rounded corners and unique facet arrangements amplify depth and warmth of hue.
Gemmological studies and market trends consistently confirm the preference for cushion cuts in coloured diamonds for this very reason — a marriage of form and fire that heightens visual allure.
The Glowing Rose, with its spectacular beauty and rarefied intrinsic structural qualities, comes from a 21-carat rough extracted in 2023, which was responsibly mined in Angola and traded under the Kimberley Process Certification Scheme. This provenance provides assurance to international collectors sensitive to exemplary sourcing.
Less than 0.01% of all diamonds are coloured diamonds with pink being one of the rarest colours to occur naturally in diamonds. Of all the diamonds submitted to Gemological Institute of America (GIA), less than 3% are classified as coloured diamonds, and of those less than 5% are considered predominantly pink – less than 0.15% of all diamonds graded by GIA. And even of the miniscule number classified as pink, only the tiniest proportion have a strong enough colour to be classified as ‘Fancy Vivid Pink,’ most of which are under 1 carat in weight. In fact, vivid pink diamonds are estimated to make up a fraction of the 0.0001% of the world’s diamond supply.
At over ten carats, this stone stands among the rarest of the rare, comparable to the celebrated pink diamonds that have set records at international auctions including most recently The Williamson Pink Star (11.15 carats) sold at Sotheby’s Hong Kong in 2022 for $57.7 million, and The Eternal Pink (10.57 carats) sold at Sotheby’s New York in 2023 for $34.8 million.
