Calcite, var. Cobaltoan Calcite

Specimen # 102214
Mineral: Calcite, var. Cobaltoan Calcite
Location: Calcite, var. Cobaltoan Calcite, Agoudal Mine, Bou Azzer District, Tazenakht , Ouarzazate, Morocco
Size: 7.9 x 5.0 x 4.9 cm


Detailed Description

Beautiful deep pink cobaltoan calcite crystals cover this specimen. Small amounts of a colourless calcite generation add contrast and offset to the pink.The display face is almost concave – it has an indent away from the viewer, as seen a bit in the photos from other angles. The cobaltoan calcite crystals are sharp and highly lustrous. In excellent condition and stands perfectly for display as photographed. With magnification, one can see lots of tiny black spherules, many of which are included within the calcite. I suspect that they may be heterogenite, but they have not been analyzed. This is a nice colourful display piece.

About These Agoudal Mine Specimens

The Agoudal Mine has been a famous source of many excellent mineral specimens for years. In particular, it has been known for beautiful cobaltoan calcite. The locality has included underground and surface workings. I understand from Tomasz Prazkier that all workings at the Agoudal Mine have now ceased. This is sad news for mineral collectors, as the Agoudal Mine has produced some of the finest cobaltoan calcites and roselites ever found anywhere.
