4.2" Polished Black Jade (Actinolite) Slab - Western Australia

This is a cut and polished slab of a type of stone that occurs at Ninghan in the Murchison region, approximately 200 miles north of the capital, Perth in Western Australia. The trade name for the stone is "Black Jade", however it isn't actually jade. Tests show that the primarily mineral in this stone is actinolite which is not a jade variety, but it can be an essential part of nephrite.

Comes with an acrylic display stand.

Actinolite is a fibrous mineral with the chemical formula Ca2(Mg,Fe)5Si8O22(OH)2. Chemically, it is very similar to tremolite, though it has more iron than magnesium.

Both actinolite and tremolite contain a form of asbestos that's made up of tiny elastic fibers. This mineral can be hazardous and should not be brought near the mouth, to avoid inhalation of the fibers. It's also suggested that you wash your hands following handling.
