Star sapphires are named for their interesting appearance of a six rayed asterisk. This star formation appears when a single light source hits the stone. This is due to needle like inclusions called rutiles. They intersect at different angles producing what is called asterism, an optical effect appearing as a star in the light reflecting from a crystal source. The largest star sapphire, named "Star of Asia", is held at the Smithsonian Museum in Washington DC. It is roughly 330 carets and almost the size of a golf ball. The ancients revered this stone and thought it to bring protection to travelers.
