Aquamarine is the blue variety of the silicate mineral beryl and therefore, like beryl, crystallizes in the hexagonal crystal system with the chemical composition Be3Al2[Si6O18].
Aquamarine gets its blue color from the presence of foreign iron ions (Fe2+ and Fe3+) at various lattice positions. As an allochromatic (foreign-colored) mineral, however, aquamarine's streak color is always white. The color named after the gemstone is a rich green-blue, but pale blue to dark blue beryls are also referred to as aquamarine.
Due to its high Mohs hardness of 7.5 to 8 and its often well-formed, clear crystals, aquamarine is mainly used to make gemstones.
