Lot Essay

Few gemstones capture the eye of collectors as powerfully as a Kashmir sapphire. Exhibiting a highly prized rich blue hue with a velvety texture unique to Kashmir stones, these sapphires display a depth of color that remain captivating under every light.

The discovery of Kashmir sapphires began in 1881, when a landslide in the Zanskar range of the northwestern Himalayas first revealed sapphire-bearing rocks. When the Maharaja of Kashmir heard of the findings of the richly colored sapphires, he quicky sent guards to protect his new mine. These sapphires became highly prized by royalty and aristocracy.

From 1882 to 1887, the mine was the source of the largest and finest stones ever discovered, making these sapphires among the rarest in the world. By 1887, the mine had been exhausted and production ceased. As a result, gem-quality Kashmir sapphires have become extremely sought after and command a much higher price premium than all other sapphires.

Christie’s has consistently showcased and auctioned some of the most exceptional Kashmir sapphires ever discovered. In May 2025, “The Regent Kashmir," a 35.09 carat cushion shaped Kashmir sapphire sold for $9.5 million in Hong Kong. This set a new world record for highest price per carat ever paid at auction for a sapphire - $271,515.

Kashmir sapphires are not merely a gemstone, but a treasure of geological and historical significance. What sets this Kashmir sapphire apart is its rare sugarloaf cut, an unconventional yet masterful shaping that enhances the sapphire’s color saturation while adding a sculptural elegance. At over 16 carats, its remarkable size and sensational cut make it a treasure and a true collector’s gem.
