Its name comes from the Greek "chrysos", which means "golden" and describes the brilliance of the stone, and "prason"meaning "leek" and describes its color.
The chrysoprase is the most valuable of the varieties of gems in chalcedony, in contrast to most of the green stones, which owe their color to chromium or vanadium, the pretty color of the chrysoprase comes from impurities of nickel , it contains micro-inclusions of minerals such as kerolite, the pimelite or the willemseite... The color varies from apple green to dark green and chrysoprase can be confused with jadeite. The chrysoprase loses its color if it is exposed to the sun or to the heat, a colouring agent, pimelitea silicate with layered structure loses easily the moisture contained in the stone. The water baths are therefore advised to retain the translucency and color of the chrysoprase.
The chrysoprase is the stone of victory, the stone ofAlexander the Great according to Albert the Great, theologian and a German naturalist of the Thirteenth century. It is cited by Pliny the elder in his natural history (circa 77) as beryl olive-green. The use of stone seems to go back to theAncient times although none of the known deposit has never been found.
The chrysoprase is the tenth precious stone of the foundation of the Jerusalem in heaven mentioned by St. John in theApocalypse.
In the Fifteenth century, the discovery of chrysoprase in Silesia (present day Poland), near Frankenstein (today Zabkowice) makes it famous, the use of stone as evidenced by the chapel of St Wenceslas from the St Vitus cathedral of Prague with its walls of large paintings interspersed with mosaics of stones : cornalines, amethysts, chalcedonies and chrysoprases.
