Gaspéite

Gaspéite is a bright grass-green to olive or yellowish green gemstone that often shows brown veining. It was first discovered near Mount Albert, Gaspé Peninsula, Québec, Canada. Most material now comes from Australia. It is a nickel carbonate and a member of the calcite group. It is often found as an intermediate material with magnesite. If the material contains more magnesium, then the stone is considered magnesite and is often called lemon magnesite in the trade. If the material contains more nickel, then it is called Gaspéite. It is found as an aggregate of rhombic crystals or massive concretions. This stone is commonly carved into artistic sculptures. This stone can be faceted or cut as cabochons and set in jewelry. It is a popular material in Southwestern inlay jewelry. It has also been found as an inclusion in chrysoprase from Tanzania.
