Natural Star Sapphire Collection – Rare Asterism Gemstones
Star Sapphires are among the most fascinating varieties of the sapphire family. Their unique asterism – the star-shaped light reflection visible on the surface – makes them highly coveted by collectors and jewelry lovers alike. Each gemstone in this collection is natural, ethically sourced, and cut to highlight the radiant or sometimes subtle star effect.
The magic of starlight
The striking star phenomenon is caused by fine rutile inclusions within the crystal, reflecting light in a six-rayed or, more rarely, twelve-rayed star. This optical effect gives every Star Sapphire its otherworldly allure, as if capturing starlight within stone.
Star Sapphires in jewelry
Usually cut as smooth cabochons, Star Sapphires emphasize the shimmering asterism over brilliance. Their silky glow and depth of color make them timeless choices for rings, pendants, and statement jewelry, admired equally by collectors and designers.
