A member of the beryl family, the aquamarine name means "sea water", which is an apt description of the colors of many aquamarine seen on the market.
It has long been considered the symbol of happiness and everlasting youth.
It was also thought to induce sleep. It has been believed that when held in the mouth, aquamarine could enable one to call a devil from hell and receive answers to any questions ask.
Water in which an aquamarine has been soaked was believed to cure eye troubles and hiccups.
Aquamarine alternates with bloodstone as the birthstone for March.
