Aquamarine is a pastel greenish-blue variety of the mineral beryl.. Its name is derived from the Latin words for water and sea. Crystals form in large hexagonal prisms. In ancient times, it was believed that sailors wearing aquamarine pendants would be protected from the perils of the sea. The stone symbolized happiness and eternal youth.
