Chrysoprase is a very rare form of quartz. Its most striking attribute is its beautiful color, that of a green apple. However it should be noted that Chrysoprase also comes in a very dark green. Chrysoprase contains traces of nickel; the nickel that is found inside the Chrysoprase is what gives it its color.
One of the reasons that Chrysoprase is so rare is due to the fact that it is a cryptocrystalline, this means that instead of being formed by large six sided crystals, the size of the crystals are extremely small and invisible to the naked eye. This attribute gives is much rarer in nature, as well as more beautiful.
Chrysoprase can come in many sizes. However, since it is rare is usually hard to come by and is generally used for smaller pieces of ornamental jewelry. During the Middle Ages, it was mined in Silesia (Northern Czech Republic and Southern Poland), the Chrysoprase that was mined were used as architectural decorations, mainly in major churches.
Chrysoprase is generally crafted as bead or spherical objects. It is sometimes cut into cabochons which are domed shaped gems, which are cut flat on the back to attach as jewelry. It is popular as a gift for those into astrology and are usually associated with Libra’s Gemini’s and Cancer’s.
One of the more popular places to find Chrysoprase is in Australia where it is mined (Queensland, Western Australia). It is usually sold as Australian Jade, due to its resemblance to this gemstone.
