CHRYSOPRASE ROUGH
This is a natural untreated piece of rough mined in West Australia.We have lightly faced one side with a 180 grit wheel to expose the colour but like all rough there is a gamble here. You can see tumbled and polished stones in our sister sites Sedagems and Mineral gem world which came from the same parcel. Weight 295.3 cts app Size 79X48X14 mm app
Chrysoprase, chrysophrase or chrysoprasus is a gemstone variety of chalcedony (a cryptocrystalline form of silica) that contains small quantities of nickel. Its color 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 color-descriptor, rather than a rigorously defined mineral variety.)
Chrysoprase is cryptocrystalline, which means that it is composed of crystals so fine that they cannot be seen as distinct particles under normal magnification. This sets it apart from rock crystal, amethyst, citrine, and the other varieties of crystalline quartz which are basically transparent and formed from easily recognized six-sided crystals
