Spheroidal growths of very lustrous rhombohedral Rhodochrosite microcrystals with an intense and uniform pink color, on matrix, with small Quartz crystals.

We will send a copy of this new analysis to the buyer.

Small, very sharp, translucent, greenish yellow crystals of Mimetite, formed by an elongated prism and an acute dipyramid. The Mimetite almost completely covers the matrix, carpeted by aggregates of white lenticular Baryte crystals.

TC2580MAR

One of the best Aurichalcite (variety zeiringite) specimens from Peramea that we know of. It comes from the collection of Adolf Bull, a chaplain from the Black Forest area in Germany, which he assembled between 1950-1965. The 'zeiringite' is on Calcite that grows on an earlier generation of cobalt-bearing Calcite that can be seen especially on the back of the piece. From a small mine in the Catalan Pyrenees, the Solita mine, located in the town of Peramea, which exploited minerals rich in cobalt and nickel.
