Jade is sometimes used as the industry name for these beautiful apple green stones because of its similarities to jade. Serpentine's luster can be greasy, waxy or silky and can sometimes be confused with nephrite jade.
Serpentine is a gem-quality hydrated magnesium silicate, usually green, yellowish-green, or brownish-green in color. It is a group of minerals which includes up to 20 different related members. Although there are a variety of serpentines, there are two basic types of serpentine which include antigorite and chrysotile. The antigorite type is a more solid stone, more attractive and durable and mostly used in jewelry making and carvings. The chrysotile type is more fibrous containing asbestos and not used for ornamental purposes. Most serpentine is opaque to translucent, with a Mohs hardness rating ranging from 2.5 to 5.5. Antigorite tends to be the harder variety. Serpentine deposits are found in several places around the world including Afghanistan, China, New Zealand, South Africa and the United States.
