The defining characteristic is the six-rayed star, known as \u201csilk\u201d, that appears to float across the surface of the gem known as asterism. To best display the star effect, star rubies are almost universally cut into a smooth, rounded, domed shape called a cabochon. In this ring the cabochon cut star ruby is complimented by twelve old mine cut diamonds that encircle it.
