1: A rare passion
Exceptional ruby and diamond ring, 17.97 carats, Burma, no heat. Estimate: CHF4,100,000–4,800,000 / US$4,800,000–5,500,000. The Geneva Jewels Auction: THREE.
A ruby weighing more than 5 carats is itself a rare find, as the rough stones are typically discovered in small sizes. Unearthing a ruby over 10 carats is exceptionally rare. But at nearly twenty carats, the present lot is a true wonder of nature, displaying exceptional clarity for a ruby of this size and a bright, well-saturated color. Two certificates and appendix letters from SSEF and Gübelin highlight its remarkable existence.
2: Bluer than the ocean
Magnificent Fancy Vivid Blue diamond ring, 3.24 carats, Internally Flawless, Type IIb. Estimate: CHF4,100,000–5,100,000 / US$4,800,000–6,000,000. The Geneva Jewels Auction: THREE.
Type IIb diamonds are characterized by the presence of boron in their crystal structure, which can impart a mesmerizing blue color. Recent research has shown that the boron atoms of such diamonds may have originally derived from ancient oceans. When considering this magnificent ring, this fact is no surprise to our eyes. To view this stone under a loupe is akin to gazing at the endless wonder of the sea. Boasting superlative certification as both Fancy Vivid Blue in color and Internally Flawless in clarity, this ring is as awe-inspiring as it is charming, elegant, and rare.
3: Rosey reverie
Fancy Intense Pink diamond ring, 5.09 carats. Estimate: CHF1,870,000–2,970,000 / US$2,200,000–3,500,000. The Geneva Jewels Auction: THREE.
To wear this stunning pear-shaped Fancy Intense Pink diamond ring is to understand the delicacy of our gaze. Expert research has shown that in 99.5% of pink diamonds, the color comes from distortion in the stone’s crystal structure, which causes our eyes to perceive the color pink, even though the chemical structure isn’t necessarily different than D-colored diamonds. It’s as if the earth is teaching us to appreciate that the highest realm of beauty lies in standing out, a lesson that lends this ring not just value and rarity but unparalleled poise and confidence as well.
4: Old world glamour
Important Fancy Intense Yellow diamond ring, 40.54 carats. Estimate: CHF850,000–1,290,000 / US$980,000–1,500,000. The Geneva Jewels Auction: THREE.
Discover the charm of the Old European cut with this Fancy Intense Yellow diamond weighing more than 40 carats. Most European-cut stones were cut by hand, lending the stone an appealing magnetism and soft, warm glow, as seen here. It’s a glistening example of the synergy between nature and the human touch that has captivated jewelry lovers for centuries.
5: Cartier: Always in style
Cartier, Very fine emerald and diamond ring, 1920s, 14.65 carats. Estimate: CHF750,000–1,000,000 / US$900,000–1,200,000. The Geneva Jewels Auction: THREE.
It’s arguably more important to be timeless than on-trend, but emeralds are having a moment right now, and perhaps that’s precisely because they’re so enduring. With strong results for emeralds seen at auction recently, this remarkable Colombian stone mounted by Cartier in the 1920s is poised to catch eyes — and bids. Now is the moment to steward this emblematic Cartier design, with its geometric stone tastefully accented by baguette diamonds, into the future.
6: A glowing enigma
Mesmerizing Fancy Dark Grey-Blue diamond ring, 3.88 carats. Estimate: CHF680,000–850,000 / US$800,000–1,000,000. The Geneva Jewels Auction: THREE.
This mesmerizing stone captures your attention and doesn’t let it go. Dancing in the light, it can appear dark grey, with glimpses of blue that flash like stars. This enigmatic play of light and color nestled between trapeze-shaped diamond shoulders presents an opportunity for a discerning collector to express themselves distinctly — with an estimate as attractive as the stone.
7: Emeralds are evergreen
Important Emerald ring, 20.49 carats. Estimate: CHF650,000–850,000 / US$750,000–1,000,000. The Geneva Jewels Auction: THREE.
Gazing into this showstopping Colombian emerald, we seem to find an endless depth. The color saturation is strong, with no indication of clarity enhancement. All told it’s simply astonishing for such a large stone, and the result is a powerful statement piece that showcases the wearer’s free spirit, creativity, and individuality.
8: The Red Miracle
‘The Red Miracle,’ Rare Fancy Red diamond, 1.21 carats. Estimate: CHF420,000–680,000 / US$500,000–800,000. The Geneva Jewels Auction: THREE.
Coming to auction from an important private collection, this glistening ring has a secret — its design centers on “The Red Miracle,” a Fancy Red diamond weighing 1.21 carats. As red diamonds weighing more than 1 carat are exceedingly rare, there’s much more to this ring than its intricate design accented by heart-shaped and brilliant-cut diamonds and circular-cut pink sapphires. Simply put, it’s a grail. All eyes will be on this ring in November as Phillips offers it on the heels of last May’s auction in Geneva, where Phillips set the record price per carat for a Fancy Red diamond with “The Argyle Phoenix” at US$2.7 million per carat.
9: A thirst for Bulgari
Bulgari, Sapphire and diamond ring, ‘Trombino’, 8.04 carat Kashmir sapphire. Estimate: CHF400,000–500,000 / US$480,000–600,000. The Geneva Jewels Auction: THREE.
By now an absolute classic, Bulgari’s ‘Trombino’ ring was devised by Giorgio Bulgari in the 1930s as an entirely diamond-set engagement ring for his Fiancée, Leonilde Gulienetti. Eye-catching and instantly recognizable, this very personal design became an instant hit with connoisseurs, and it remains so today. But what could be better than such a classic design set with a Kashmir sapphire weighing more than 8 carats? By featuring a sapphire of the most sought-after origin within Bulgari’s distinctive savoir-faire, the result is a uniquely desirable ring that is unrestrained in its allure.
