Aquamarine

The name of the mineral derives from Latin 'aqua marina' meaning sea water and refers to the blue-greenish color of the stone. Aquamarine is a variety of beryl, just like emerald and heliodor. Its pale blue color is attributed to Fe2+. The stone is valued not only for its color and transparency, but also for its hardness.
