Psilomelane

The stone of shadow and depth

The smooth black manganese stone, known in tradition as a stone of shadow, inner reflection and growth.

Psilomelane is a name for hard, black oxides of manganese and barium, romanechite among them. It forms rounded, kidney-shaped masses with a smooth, dull-metallic surface, sometimes banded with grey pyrolusite. The name comes from the Greek psilos, "smooth", and melas, "black". Today it is treated as a group name rather than a single mineral, and it is found in the USA, Mexico, Germany, Australia and South Africa. It is often mistaken for black hematite, but the two are unrelated.
