Aquamarine is a pale-blue to light-green variety of the beryl family. It is transparent to translucent and possesses a hexagonal crystal system. Aquamarine is a fairly common gemstone, rendering it more accessible for purchase, compared to other gems in the beryl family.
Aquamarine mainly forms in granite pegmatites and hydrothermal veins, a process that takes millions of years and is associated with Precambrian rocks.

Beryl (/ˈbɛrəl/ BERR-əl) is a mineral composed of beryllium aluminium silicate with the chemical formula Be3Al2(SiO3)6. Well-known varieties of beryl include emerald and aquamarine. Naturally occurring hexagonal crystals of beryl can be up to several meters in size, but terminated crystals are relatively rare. Pure beryl is colorless, but it is frequently tinted by impurities; possible colors are green, blue, yellow, pink, and red (the rarest). It is an ore source of beryllium.
