Men's Star Sapphire Ring, 15.30 Carats

A six-rayed "star" shines brightly at the center of this 15.30-carat cabochon star sapphire. The blue gemstone is among the most unique variety of sapphires thanks to its asterism, an optical phenomenon that produces its eponymous star. Microscopic needle-like mineral inclusions are found in the stone, and it is these that perfectly align to cause the appearance of a star when the gem is viewed under a concentrated light source. This rare gem is set in a bold platinum setting with diamond accents totaling approximately 0.10 carat.
