Over at Christie’s, Harry Winston dazzled bidders with a remarkable pair of spinel and diamond earrings. The Tanzanian spinels, weighing 22.42 and 21.87 carats respectively, are unheated and untreated, making them a rarity in the gemstone market. Set in platinum and 18-karat yellow gold, the earrings’ near-matching quality added to their appeal. While Burmese spinels continue to dominate the category, the size and quality of these Tanzanian stones, coupled with the Harry Winston name, drove their final sale price to $2,228,000.
Another standout at Christie’s was a stunning Cartier brooch from 1914, which surpassed its top estimate of $150,000 to sell for $1,381,000. The platinum brooch, adorned with a natural pearl, briolette-cut pink tourmaline, carved ruby, carved onyx, and old and single-cut diamonds, came from the collection of the late interior designer and philanthropist Mica Ertegun. The piece’s provenance and intricate craftsmanship made it a highly coveted lot. Additionally, Ertegun’s collection featured several sought-after Belperron pieces, further elevating the auction’s appeal.
