Emerald

Emerald is a gemstone and a variety of the mineral beryl (Be₃Al₂(SiO₃)₆) 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.

Etymology

The word "Emerald" is derived (via Old French: Esmeraude and Middle English: Emeraude), from Vulgar Latin: Esmaralda/Esmaraldus, a variant of Latin Smaragdus, which originated in Greek: σμάραγδος (smaragdos; "green gem").

Properties determining value

Emeralds, like all colored gemstones, are graded using four basic parameters–the four Cs of Connoisseurship: Color, Cut, Clarity and Carat weight. Before the 20th century, jewelers used the term water, as in "a gem of the finest water", to express the combination of two qualities: color and clarity. Normally, in the grading of colored gemstones, color is by far the most important criterion. However, in the grading of emeralds, clarity is considered a close second. Both are necessary conditions. A fine emerald must possess not only a pure verdant green hue as described below, but also a high degree of transparency to be considered a top gem.

Jewels (ballet)

Jewels is a three-act ballet created for the New York City Ballet by co-founder and founding choreographer George Balanchine. It premièred on Thursday, 13 April 1967 at the New York State Theater, with sets designed by Peter Harvey and lighting by Ronald Bates.

Jewels has been called the first full-length abstract ballet. It has three related movements Emeralds, Rubies, and Diamonds (usually separated by intermissions). It can also be seen as three separate ballets, linked by their jewel-colored costumes. Balanchine commented: "The ballet had nothing to do with jewels. The dancers are just dressed like jewels." Each of the three acts features the music of a different composer: Emeralds is set to the music of Gabriel Fauré, Rubies to the music of Igor Stravinsky and Diamonds to music by Pyotr Ilyich Tchaikovsky.

Emeralds (band)

Emeralds was an American electronic music trio founded in 2006 by members John Elliott, Steve Hauschildt and Mark McGuire. The band was based in Cleveland, Ohio and Portland, Oregon, United States.

History

Emeralds was noted for drawing from both ambient music and Kosmische, and minimal music.

John Elliott, Steve Hauschildt and Mark McGuire began playing music together under the name Fancelions in 2005 in Cleveland's western suburbs of Bay Village and Westlake. Shortly thereafter, they re-formed as Emeralds, playing their first show under that name in June 2006. Since then the group has released over forty recordings on various independent labels. The album Does It Look Like I'm Here?, released on Editions Mego in 2010, is their most widely known release to date. It received the Best New Album designation from Pitchfork Media, the Album of the Year award from Drowned in Sound, and accolades from many other publications. Mark McGuire and Steve Hauschildt also perform and record under their own names, while John Elliott does so under a number of monikers including Outer Space and Imaginary Softwoods. The band also maintains multiple labels including McGuire & Elliott's Wagon, Hauschildt's Gneiss Things and Elliott's curated imprint Spectrum Spools.
