The blue-green to pale blue color of this stone, which like emerald, is a silicate of aluminum and beryllium, inspired its name (“sea water”). The Indians and Ancient Egyptians sculpted it into amulets. Greek legend tells how seahorses stole these aquatic stones from the nymphs’ treasure and scattered them on shores where men would find them. Aquamarine has always been said to protect those at sea.
Cartier made this stone its own in the 1930s. One of the jeweler’s customers, Elsie de Wolfe, dyed her hair blue to match the diamond and aquamarine tiara which Cartier created for her in 1935.Hardness: 7.5.
