Chrysoprase is a type of chalcedony that has traces of nickel. Nickel is found in the form of very small inclusions. It is a cryptocrystalline form of silica. Generally, the color of Chrysoprase is apple-green, but it is also found in deep green color. Chrysoprase is derived from the Greek language, where ‘chrysos’ means ‘gold’ and ‘prassinon’ means ‘green.’ It rates between 6 to 7 on the Mohs hardness scale. This gemstone is found all across the globe, with some of the notable deposits being in Australia, Brazil, Central Europe, North America, and South Africa. It’s also known as “Australian jade” since it is prominently mined in Western Australia and closely resembles a few vibrant East Asian stones.
