Black Star Sapphire is a captivating gemstone, renowned for its mysterious allure and celestial phenomenon known as asterism. This enchanting effect, where a star-like pattern dances across its surface, is best observed in cabochon cuts, which enhance its natural beauty. Our Black Star Sapphires originate from Thailand, a region celebrated for producing stones of deep black hue and exceptional clarity.
Unheated and untreated, these sapphires maintain their natural integrity, offering a pure expression of their geological journey. The value of Black Star Sapphire is driven by the intensity of its star effect, the depth of its colour, and the quality of its cut. Many of our stones are accompanied by a certificate from the GIT, with additional certification available upon request. Prices for these exquisite gems start from around $15 per carat, reflecting their unique charm and rarity.
