BOULDER CHRYSOPRASE 925 STERLING SILVER JEWELLERY

Chrysoprase is a cryptocrystalline quartz gemstone that is a type of Boulder chalcedony. The spectrum of transparency is from almost opaque to nearly transparent. It comes in a variety of shades, from apple to olive green, as well as practically pure greens with middling tones. While some chalcedony variations, like Zimbabwe's "mtorolite," acquire their green hue from chromium, chrysoprase gets its color from nickel. The term "dark chrysoprase" is sometimes used to designate chrysoprase gems with darker tones. Praise is also used to describe green chalcedonies with chlorite inclusions that are found in Europe.
