1.66 Carat Pink Pear Sapphire

This is a 1.66-carat pink sapphire in pear shape, offered as a loose stone. The stone has been heat-treated, a standard practice in sapphire production that improves color stability and clarity. Pink sapphires are corundum varieties that derive their hue from chromium content within the crystal structure. The stone is available through Leibish, a retailer specializing in colored gemstones.
