Aquamarine’s name was derived from the Latin words, "Beryllus Aquamarinus" literally mean “water of the sea”, a reference to its delicate blues hue. The gem increased in popularity around 1920 when heat treatment was developped to turn pale greenish stones to deeper blue shades.
Different shades of Aquamarine are distinguished by their own names, for instance “Santa Maria” is the name of the extremely rare, intensely deep blue Aquamarine found in Brazil.
Brazil has traditionally been the world’s major supplier of Aquamarine, although today several African nations provide a supply of similarly beautiful materials. Aquamarines' color caused by trace amounts of iron, Aquamarine is a member of the Beryl family whose members also include Bixbite, Goshenite, Emerald, Heliodor & Morganite.
