Some sapphires contain unusual tiny needle-like inclusions, and are cut in a cabochon shape to display a dancing six-rayed white star. Star sapphires, which are becoming more rare, are very popular for men's rings. Star sapphires are judged by the sharpness of the star, the evenness of the rays or "legs" of the star, and the body color of the sapphire. It is extremely rare to find a star-sapphire with a sharp star and a bright blue body color. The ancients regarded star sapphires as a very powerful talisman, a guiding star for travelers and seekers of all kinds. They were so powerful, they were said to continue to protect the wearer even after being passed on to someone else.
