Description

A classic locality specimen of a talc matrix that has been carved to expose white and black crystals of breunnerite, a ferroan variety of magnesite. Crystals are well exposed around in all faces of the matrix, so it can be presented in different positions. Remarkably, some magnesite crystals have a white colour, probably due to a lesser amount of iron in the structure and others are even bicoloured, which is uncommon.

Acquired in 1978. Ex Georges Vanacker #v969.
