Chrysophrase

The Chrysophrase is fairly popular with the jewellers but not well known in general. With it mystriosly clear, mild green colour with depht it is totally unique. The supply of cut cabochons on the common market is very low and the quality is not the highest (the best stones is normally swept up by large purchasers). But sometimes we get lucky and then we don't hesitate.

Chrysoprase, crysophrase or chrysoprasus is a gemstone variety of chalcedony (a cryptocrystalline form of silica) that contains small quantities of nickel. Its colour is normally apple-green, but varies to deep green. The darker varieties of chrysoprase are also referred to as prase. (However, the term prase is also used to describe chlorite-included quartz, and to a certain extent is a colour-descriptor, rather than a rigorously defined mineral variety.)

Chrysoprase consists of crystals, so fine that they can not be seen as distinct particles at normal magnification. This sets it apart from rock crystal, amethyst, citrine and other varieties of crystalline quartz which are basically transparent and formed from easily recognized six-sided crystals. Other members of the cryptocrystalline family is the agate, carnelian and onyx. Unlike the emerald with its green colour of chromium, wearing chrysoprase trace amounts of nickel compounds in the form of very small inclusions.

The most known deposits of chrysoprase are Queensland Australia, Germany, Poland, Russia, Arizona, California and Brazil. Deposit in Szklary, Lower Silesia, Poland, was probably the largest European presence and possibly the largest in the world. A closely similar to the mineral chalcedony chrysoprase is where the colour comes in chrome rather than nickel.

Chrysoprase stands for protection and health.
