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

Its blue color in aquamarine is due to foreign inclusions of divalent and trivalent iron ions (Fe2+ and Fe3+) in different lattice positions. As an allochromatic (foreign-colored) mineral, the streak color of aquamarine is always white. The color tone named after the gemstone is a saturated green-blue, but pale blue to dark blue beryls are also called 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.
