Aquamarine is the blue variety of the silicate mineral beryl and therefore crystallizes in the hexagonal crystal system with the chemical composition Be3Al2[Si6O18].

Its blue color is due to trace inclusions of divalent and trivalent iron ions (Fe2+ and Fe3+) at various lattice positions. As an allochromatic (foreign-colored) mineral, the streak color of aquamarine is always white. The color name named after the gemstone is a vivid 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 primarily processed into gemstones for jewelry.
