(gcide) | Beryl \Ber"yl\ (b[e^]r"[i^]l), n. [F. b['e]ryl, OF. beril, L.
beryllus, Gr. bh`ryllos, prob. fr. Skr. vai[dsdot][=u]rya.
Cf. Brilliant.] (Min.)
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 aluminum and 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.

beryllium
(gcide) | Glucinum \Glu*ci"num\, n. [Cf. F. glucinium, glycium, fr. Gr. ?,
sweet. Cf. Glycerin.] (Chem.)
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. [Formerly written also
glucinium.]
