The Pink Star diamond ring is renowned as the most expensive ring ever sold, featuring a remarkable 59.60-carat Fancy Vivid Pink diamond set in platinum with two white diamonds at its sides[1]. The Pink Star was discovered in 1999 in South Africa by De Beers, and after 20 months of cutting and polishing by Steinmetz Diamonds, was revealed in Monaco in May 2003[1].
This extraordinary pink diamond is classified as internally flawless, earning the highest possible color and clarity gradings for a stone of its kind[3]. The Gemological Institute of America declared it the largest Flawless Fancy Vivid Pink diamond they had ever graded[1].
The Pink Star made headlines at auctions multiple times. In 2013, it was sold in Geneva for a record $83 million, though the buyer was unable to complete the payment[1]. It later returned to Sotheby’s and, in April 2017, sold again—this time to Chow Tai Fook Enterprises, a Hong Kong-based jewelry retailer, for $71.2 million at Sotheby’s Hong Kong[2][3][5]. At this sale, the diamond was renamed the “CTF Pink Star” to honor Chow Tai Fook’s founder[3].
The Pink Star’s status as a Type IIa diamond (containing no nitrogen impurities) adds to its rarity and value[3]. Its cut is oval, and its measurements are approximately 2.69 cm x 2.06 cm[1]. The diamond’s vivid hue is thought to result from natural crystal lattice distortions during formation, making pink diamonds both chemically and visually unique[3].
The Pink Star ring stands as a symbol of rarity, meticulous craftsmanship, and the pinnacle of luxury, combining size, color intensity, and flawless clarity in a single, breathtaking piece that is coveted by collectors and investors alike[1][3][5].
