| Aquamarine is the blue, or perhaps more correctly, blue-green or aqua variety of the mineral beryl. Other gemstone colour varieties that belong to beryl include emerald, morganite, and heliodor. Other colours of beryl are simply referred to by their colour, such as red beryl. Hardness: 7.5-8. Other characteristics.

These really are quite perfect (the white bumps would easily be discarded, had I the dexterity!) and is a much more aqua colour than this photo suggests Aquamarine is coloured by trace amounts of iron that find their way into the crystal structure. Most gem aquamarines have been heat treated to produce the popular blue-green colours from less desirable yellow or pale stones. The leading producer of aquamarines is the country of Brazil, which has many mines. Pakistan, as well as many U.S. localities, produce wonderful specimens as well.
