What is "emerald"

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]ry

1. 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.

"bright green precious stone," c.1300, emeraude, from Old French esmeraude (12c.), from Medieval Latin esmaraldus, from Latin smaragdus, from Greek smaragdos "green gem" (emerald or malachite), from Semitic baraq "shine" (compare Hebrew bareqeth "emerald," Arabic barq "lightning").\n

\nSanskrit maragdam "emerald" is from the same source, as is Persian zumurrud, whence Turkish zümrüd, source of Russian izumrud "emerald." For the excrescent e-, see e-.In early examples the word, like most other names of precious stones, is of vague meaning; the mediæval references to the stone are often based upon the descriptions given by classical writers of the smaragdus, the identity of which with our emerald is doubtful. [OED]\nEmerald Isle for "Ireland" is from 1795.

a. Of a rich green colour. n. Any of various green gemstones, especially a green transparent form of beryl, highly valued as a precious stone.

Emerald is a gemstone and a variety of the mineral beryl (BeAl(SiO)) colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor. It is a cyclosilicate.

Emerald is a green gemstone. Because of its color, the word emerald is often used to describe a shade of green.

Emerald may also refer to:

The Emerald mango is a named mango cultivar that originated in southwest Florida.

Emerald is a distributed, object-oriented programming language developed in the 1980s by Andrew P. Black, Norman C. Hutchinson, Eric B. Jul, and Henry M. Levy, in the Department of Computer Science at the University of Washington.

A simple Emerald program can create an object and move it around the system:

const Kilroy ← object Kilroy
process
const origin ← locate self
const up ← origin.getActiveNodes
for e in up
const there ← e.getTheNode
move self to there
end for
move self to origin
end process
end Kilroy

Emerald was designed to support high performance distribution, location, and high performance of objects, to simplify distributed programming, to exploit information hiding, and to be a small language.

Emerald is the ninth studio album by singer/songwriter Dar Williams, released in 2015 by Bread & Butter Music.

Emerald is the 23th album by Breton musician Alan Stivell, released in 2009. The album celebrates Stivell's 40-year career ( Emerald wedding) since 1970's Reflets (Reflections), his first album as a singer. It's a return to the roots, a return to the violin and to folk-rock ( Chemins de Terre), and both an ever innovative approach, playing on electric harp and bagpipes prototypes and in musical arrangements that are as eclectic as they are original.
