 HISTORY and LORE

  • Name comes from Latin aqua marina meaning “sea water.” To the ancient Greeks and Romans aquamarine embodied the spirit of the sea. In some stories it was a treasure protected by the mermaids.
  • During the Middle Ages, Europeans believed this gem gives its wearer wisdom and inspiration, power to overcome evil, and ability to see the future. According to other traditions, aquamarine creates harmony and ensures a long, happy marriage. Its bright, refreshing color made it a symbol of eternal youth.
  • Birthstone for March and gem for the 19th wedding anniversary.
