The auction house is offering a Bulgari ring featuring a 24-carat pink diamond for sale in Geneva.<\/h2>\n

For years, pink diamonds have been the most prized stones among collectors and gem enthusiasts. Now, Christie\u2019s in Geneva is auctioning an exceptional stone: a 24-carat, emerald-cut, Fancy Intense Pink diamond set in a Bulgari ring. The diamond will be offered on November 10 at the *Magnificent Jewels* auction at the Four Seasons Hotel des Bergues, with an estimated value of $12\u201318 million. The diamond was part of the collection of a distinguished European noble family and has remained in private hands for over 70 years.<\/p>\n

According to family tradition, the rough diamond was purchased in India in the 1950s by the current owner’s great-grandfather and subsequently entrusted to Bulgari, who used it to create the current ring. At the time, Bulgari was establishing itself as a destination for some of the world\u2019s most discerning collectors and patrons, making it the natural choice for a diamond of such rarity.<\/p>\n

The Largest Pink Diamonds<\/h2>\n

The origin of pink diamonds is a subject of much debate within the world of gemology. The prevailing theory suggests that the color results from the shear stress these diamonds undergo during their formation; however, other research attributes the distinctive hue to radiation exposure. One of the most famous pink diamonds is the 59.60-carat Pink Star, the largest of its kind in the world. It was sold at auction for $88 million in 2014, but the buyer failed to complete the payment and was subsequently forced to forfeit the purchase. Other notable pink diamonds include the Daria-i-Noor\u2014the world’s largest pink diamond, with an estimated weight of 182 carats\u2014and the Noor-ul-Ain, the oldest known pink diamond; both are part of the Iranian Crown Jewels.<\/p>","protected":false},"excerpt":{"rendered":"
