Beryl is a mineral and in certain varieties a valuable gem material. It consists of aluminum berllyium silicate, Be3Al2(SiO 3)6, and it is the chief commercial ore of beryllium.

Pure beryl is colorless and transparent. Emerald, a most valuable gem, is green with traces of chromium in it. Aquamarine, likewise a gemstone, is blue in color but less valuable than the emerald. There is a golden beryl and morganite or rose beryl that are even less valuable. Sometimes the colorless beryl is sold under the name of goshenite.

Beryl helps heal liver complaints and diaphragm ailments. (see Gem HealingA.G.H.
