Like most gemstones, aquamarine forms in igneous rocks. As the pluton cools, minerals form crystals, the slower the cooling the larger the crystals. The beryl group is often found in pegmatitic rocks (rocks with very large, distinct crystals).

is a gemstone-quality transparent variety of beryl, having a delicate blue or turquoise color, suggestive of the tint of seawater. It's closely related to the gem emerald. Colors vary and yellow beryl, called heliodor; rose pink beryl, morganite; and white beryl, goshenite are known.
