RM2992   Arsenopyrite and chalcopyrite

Julcani Mine, Julcani, Angaraes, Huancavelica, Perú

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. Good sized specimen.


Size: 11,5 x 5.7 x 4.4 cm.

RM1379   Arsenopyrite with chalcopyrite and ferberite

Julcani, Angaraes, Huancavelica, Perú

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.
