Be₃Al₂(SiO₃)₆
Beryl is a name to describe the 7 minerals that are composed of beryllium aluminum silicate. These seven minerals are Emerald, Aquamarine, Morganite, Goshenite, Bixbite, Heliodor and Pezzottatie. Being a relatively rare silicate mineral, many varieties of Beryl are considered valuable gemstones. Beryl is often found forming in granites and granitic pegmatites, but it has also been found forming in metamorphic rocks as well as veins and cavities of limestone and marbles.
