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.

This is a selection of cabochons that have a rim of Australian black jade, many
inlayed with mookaite. They are the work of skilled lapidarist, Ron Gibbs.
