This rare and yet magnificent subset of Rubies is referred to as Star Rubies because of the phenomenal stars the stones naturally display. Each stone has its own character, with respect to body color or sharpness of its star. When placed under focused light, a star can be seen forming perfectly oriented 6 rayed or 12-rayed stars. As mystical as the gem may seem, the star we see is formed by needle inclusions that reflect light also known as silk. Just as in the case of rubies, Star rubies are also heated to improve the color of the gem, although untreated gems are highly valuable. Star Rubies have been known to recharge your energy and stimulate the mind.
