RM1511   Goethite

Corta Filón Sur, Tharsis, Alosno, Huelva, Andalucía, Spain

RM1390   Axinite-(Fe) with calcite and quartz

Colebrook Hill Mine, Colebrook Hill, Rosebery, Tasmania, Australia

If something I like about the world of selling minerals is to find specimens lost in the nooks of old collections. This sample is a case of this. It is an Australian piece, of good size, formed by a druse of ferro-axinite crystals, not very big, but with an excellent color and transparency. They are accompanied by calcite and curious milky quartz. The specimen comes from a locality located NW of Queenstown, Tasmania, a big skarn that was worked by their sulfides: pyrite, pyrrhotite, arsenopyrite, chalcopyrite. Under the calcite ferro-axinite appeared... But a long time ago.

RM1379   Arsenopyrite with chalcopyrite and ferberite

Julcani, Angaraes, Huancavelica, Peru

These specimens of Peruvian arsenopyrite stand out for their excellent luster and perfection of its crystals. With the camera I am not able to capture its real beauty. On a sulfide matrix we can enjoy hundreds of arsenopyrite crystals, prismatic, with defined terminal faces, rather than well-defined. They're accompanied by chalcopyrite crystals with dull luster, but gold tone, also well-defined and twinned. Brilliance and quality. A novelty of Sainte-Marie-aux-Mines 2016.
In this sample we see aggregates of intense black color and metallic luster which analysis indicates that it is ferberite (with minor % Mn). Simply outstanding.


Size: 6.5 x 6.3 x 4.0 cm.
Main crystal: 5 x 2 mm.
Found in 2016.
