Sapphire is the blue form of corundum. Yellow, pink and green forms of the gem, know as “fancy sapphires” also exist. The finest sapphires have a brilliant, deep, velvety blue colour. Like the star ruby, the star sapphire is a translucent variety which produces a six-pointed star effect when cut as a cabochon (dome).
Sapphire is the symbol of the heavens and was believed to bestow innocence and chastity.
