From Webster's Revised Unabridged Dictionary (1913) (web1913)
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 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.
