Star Ruby. Oriented rutile crystal inclusions cause a six-rayed-star light effect (called asterism) to form the popular "Star Ruby". The "Star Ruby" is also known as a "Mysore Ruby", as the majority are mined in Mysore, India. Ruby was worn by the ancients as an amulet for protection from plagues, poison, sorrow, and evil spirits. The ruby symbolized freedom, charity, dignity and divine power. The Greeks believed that the "fire" evidenced by a ruby's red coloration could melt wax. Up through Medieval Europe, rubies were worn for protection against unhappiness, lightening and upsetting dreams.
