Geology

Black jade – is an Amphibolite and has been formed by extreme metamorphism of the Archaean greenstone rock. It is a very dark green/black fine grained rock and has a wide range of uses.

Key Elements

Western Australian “black jade” occurs at Ninghan in the Murchison region approximately 200 miles north of the capital, Perth.

The rough “jade” has a brown, rust stained skin but once cut and polished, the best material is like a black mirror.

Tests have shown that the stone is actinolite, not nephrite.
