Nefrite Donut Pendant measuring 4 cm
Nefrite
Nefrite is a compact, fibrous variety of the amphibole mineral actinolite, and is classified together with jadeïet as jade. The mineral usually has a green to grey-green appearance, with a silky luster and a characteristic toughness, making it suitable for working and decorative applications. Nefrite has been loved for centuries in Chinese art and culture, among others.
Major deposits of nephrite include China, New Zealand, Canada, Russia and the United States. The mineral is formed by metamorphic processes, often in areas where serpentine occurs. Its chemical formula is Caâ‚‚(Mg,Fe)â‚…(OH)â‚‚, and its hardness is between 6 and 6.5 on the Mohs scale.
