Serpentine
Serpentine is a group of minerals formed by the hydrothermal conversion of olivine and pyroxene in ultramafic rocks. Its colour ranges from light green to dark green, sometimes with a marble-like pattern. Serpentine has a waxy to silky luster and a smooth surface, making it popular for decorative use and sculpture.
Major deposits of serpentine include China, Italy, Afghanistan, the US and South Africa. The chemical composition varies, but common forms are antigorite, lizardite and chrysotile. The general formula is (Mg,Fe)₃Si₂O₅(OH)₄. Serpentine has a hardness of 2.5 to 5.5 on the Mohs scale, depending on the variety.
A popular variety is "New Jade", a trade name for a light green form of serpentine often used as an alternative to jade in jewellery and decorative objects. So, despite the name, it is not real jade, but serpentine with a jade-like appearance.
