A magnificent sapphire and diamond necklace was the star of Christie’s recent Magnificent Jewels auction in Hong Kong, realising HKD 125.5 million (USD 16.1 million) and comfortably landing within its estimated range.
The centrepiece features 16 antique, cushion-shaped Kashmir sapphires, ranging from 3.43 to 13.37 carats—coveted for their velvety saturation and rarity. Each sapphire is framed by an array of D–F colour, internally flawless to VS1 diamonds, with a combined diamond weight of 121.81 carats.
According to Christie’s, the necklace dominated the 25 November sale and drew significant attention from collectors seeking exceptional provenance and craftsmanship.
The auction totalled HKD 538.1 million (USD 69.1 million), showcasing important creations from renowned maisons including Harry Winston, Van Cleef & Arpels, Cartier, and JAR.
