Chrysocolla is a hydrous copper silicate, often forming with copper salts, iron and manganese oxides. This natural gemstone is known to form in oxidation zones of copper ore bodies and is actually considered a minor ore for the mineral copper. Although Chrysocolla may be a 'lesser known' gemstone, it is still a very fascinating stone that is highly sought-after by many avid gem and mineral enthusiasts. It should not be fired, and should be set after firing.
