Beryl is a mineral composed of beryllium aluminium silicate with the chemical formula Be3Al2(SiO3)6. Its well-known varieties include emerald and aquamarine. Naturally occurring hexagonal crystals can reach several meters in size, although terminated crystals are relatively rare. Pure beryl is colorless but is frequently tinted by impurities, with green, blue, yellow, pink and red (the rarest) all possible, and it is an ore source of beryllium. In this atlas it is the mineral species that gemstones such as emerald and aquamarine record.
