CEYLONMINE-Gemstone 5.5 Carat / 5.25 Ratti Natural & Precious Star Ruby Gemstone Lab Certified

Star ruby is a rare variety of ruby that exhibits asterism; a six-rayed star that shimmers over the surface of the stone when it is moved. The star effect is owed to aligned needle-like rutile inclusions. It is the rutile which is responsible for its silky shine.
