Star ruby

A variety of ruby that has a silky structure and when cut en cabochon shows a 6-rayed (rarely, 12-rayed) star in reflected light, due to the phenomenon known as asterism. Such stones are natural or a synthetic gemstone. Among important star rubies are the De Long Star Ruby and the Rosser Reeves Star Ruby.
