information on charoite
Charoite was discovered in 1976 along the Charo River in Siberia.
The black needle-like inclusions are aegirine-augite, the orange-colored
patches are tinkasite, and the transparent zones are microcline feldspar.
Because of its fibrous nature, charoite has a tendency to chip and splinter
Consequently, it needs to be worked with diamond abrasives.
