Semi Precious Stone Jade

An ornamental stone, jade is a name which is applied to two different silicate minerals. Nephrite is a form of the amphibole actinolite (a mineral that also includes a form of asbestos). The second, the mineral jadeite, is the pyroxene. Nephrite has the formula Ca2 (Mg, Fe) 5Si8O22 (OH) 2. Jadeite has a formula NaAlSi2O6. The two are quite similar in appearance and normally it wasn't until 1863 that the two forms of this gemstone were distinguished.
