Olivine and Kammererite Display Piece

A display specimen of olivine with kammererite from Aheim, Norway. Olivine is a mineral which often forms in the subsurface of the earths crust, for this reason, it is often unstable on the earths surface and thus weathers easily. The depth at which it forms also results in samples being quite dense for their size. It derives its name from it’s green colour which is a result of nickle and is found in mafic and ultra mafic igneous environments. When high quality crystals are found, they are known as peridot and are highly sought after as gemstones, as they can be cut, shaped and polished with drastic effects, enhancing the green colour further more. Kämmererite is a variety of chromite, which is often found in massive form. It possess unique properties and characteristics which make it desirable. Firstly, the varying abundance of chrome contributes to a shift in colour from a dull grey to shimmering silver – and even to a deep purple. This sample features kammeritrite that has formed attractive band like patterns within the olivine. The piece measures roughly 13 x 12 x 3.5 cm at its widest points and weighs approximately 1.199 kg. This specimen is supplied with an information label and will make an ideal display piece.
