DescriptionAquamarine Be3Al2Si6O18 is the blue to blue-green or aqua variety of the mineral beryl. Aquamarine is colored by trace amounts of iron that find their way into the crystal structure. The environment that beryl is found in is mostly granitic pegmatites. Gem aquamarines can be heat treated to produce a more desireable color from lesser pale colored stones. Its name comes from the ancient Greek, beryllos, signifying a “precious blue-green color of sea water” stone.
