n.
A mineral of great hardness, and, when transparent, of much beauty. It occurs in hexagonal prisms, commonly of a green or bluish green color, but also yellow, pink, and white. It is a silicate of aluminium and glucinum (beryllium). The aquamarine is a transparent, sea-green variety used as a gem. The emerald is another variety highly prized in jewelry, and distinguished by its deep color, which is probably due to the presence of a little oxide of chromium.
n.
A rare metallic element, of a silver white color, and low specific gravity (2.1), resembling magnesium. It never occurs naturally in the free state, but is always combined, usually with silica or alumina, or both; as in the minerals phenacite, chrysoberyl, beryl or emerald, euclase, and danalite. It was named from its oxide glucina, which was known long before the element was isolated. Symbol Gl. Atomic weight 9.1. Called also beryllium.
n.
A metallic element found in the beryl. See Glucinum.
