Sotheby’s is to offer for sale the largest fancy vivid orangy pink diamond ever graded, at a debut event in Abu Dhabi in December.
The pear-shaped gem, known as the Desert Rose, weighs 31.86 carats and is expected to fetch $5m to $7m.
It is the jewelry highlight of Sotheby’s inaugural Abu Dhabi Collectors’ Week of exhibitions, sales, masterclasses and panel discussions.
The Desert Rose is part of a single-owner collection of watches and jewelry, including vintage and contemporary signed pieces, that is estimated to raise more than $20m in total.
Among the watch highlights is an exceptionally rare Rolex “Oyster Albino” Daytona, reference 6263, produced in the late 1960s and early 1970s, with an estimate of $500,000 to $1m.
Abu Dhabi Collectors’ Week takes place from 2 – 5 December on Saadiyat Island, just off the Abu Dhabi coast.
It coincides with the Abu Dhabi Grand Prix and features auctions of collector cars, real estate, and international fine art exhibitions.
The Kao Legend Collection represents an extraordinary achievement in diamond cutting and curation. Cut from a single 108.39-carat pink diamond crystal unearthed at the renowned Kao Mine in Lesotho, this suite features seven magnificent pink diamonds each documented in detail by the GIA Monograph.
At the heart of the collection lies the Kao Legend, a 20.49-carat diamond graded Fancy Intense Purplish Pink by the Gemological Institute of America (GIA). The accompanying diamonds in the collection range in colour from Fancy Intense Purplish Pink to Faint Pink, showcasing a delicate and rare spectrum of pink hues.
What sets this collection apart is not only its shared origin and harmonious beauty but also the diamonds’ classification. All seven are Type IIa diamonds known for their exceptional chemical purity and rarity, comprising less than 2% of all natural diamonds. Type IIa pink diamonds are especially coveted for their remarkable clarity and vibrant colour saturation.
The Kao Mine, one of Lesotho’s most prominent diamond sources, has established a reputation for yielding high-quality pink diamonds. Alongside the Kao Legend, the mine also produced the celebrated Pink Eternity, a 47.80-carat gem of international acclaim.
For gemmologists and collectors alike, the Kao Legend Collection exemplifies nature’s artistry and the pinnacle of diamond excellence.
