Nephrite is a cryptocrystalline mineral of calcium magnesium iron rich silicate with hydroxyl: Ca (Mg Fe)5 Si8O22(OH)2. It is part of the amphibole group, in the fibrous variety of the tremolite-actinolite mineral series.
There are two primary types of gemstome with the name of ‘jade’ – nephrite and jadite. Jadite is probably what you’re most used to seeing in figurines. Jadeite is a polycrystalline sodium aluminium silicate: NaAl(SiO3)2 and is part of the pyroxene group. Jadeite is rarely found pure and is generally a rock primarily of jadeite with small amounts of other minerals, notably kosmochlor and omphacite. There is another type of gemstone that is labelled as ‘jade’, and this is chrysoprase. The chrysoprase we stock comes from Australia and is commonly known as ‘Australian Jade’.
Nephrite jade is important in China, and has historically been mined from the Kulun Mountains in Western China. We also stock nephrite puff hearts from Australia.
