The term jade is used for jadeite and nephrite jade. For centuries the two materials were considered one and the same. It was not until 1863 that they were identified as different minerals with a similar appearance and properties. Jadeite jade is a member of the pyroxene group and is primarily composed of the mineral jadeite. Nephrite is a tough rock comprised of intergrown crystals of minerals from the tremolite-actinolite solid solution series, part of the amphibole group.
