[ what's this? ]
Chysoprase is the green gemstone in the chalcedony family, which is a cryptocrystaline quartz. That means that it is a quartz, but unlike transparent varieties like amethyst or citrine, it is made of teeny tiny crystaline particles and looks more like a glowing rock rather than a geometric crystal shapes. It is always milky-translucent or opaque, never perfectly clear. Its green color is unique among green gemstones – a cool light apple green to dark forest green. It has been used in jewelry for thousands of years – by the Romans, and Ancient Egyptions. Its name comes from the greek “chrysos” (meaning: gold) and “prasinon” (meaning: green). Of all the gemstones in the Chalcedony family, chrysoprase is the most precious. The most famous, large and historic mine is in Poland, but many believe the finest comes from a more recent discovery in Western Australia.
The most important factor in determining the value of chrysoprase is its color. After color, translucence and size will have strong influence.
