RM1377   Arsenopyrite with chalcopyrite

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.


Size: 7.8 x 5.0 x 3.5 cm.
Main crystal: 5 x 2 mm.
Found in 2016.

 

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.

RM1045   Siderite with chalcopyrite

Julcani Mine, Julcani, Angaraes, Huancavelica, Peru

Aesthetic specimen of chalcopyrite, very brilliant, with defined but complex crystals, on which a well developed rhombohedral siderite have grown, interpenetrating and showing rough faces. They show a uniform honey color. These specimens on matrix are rarely seen in the market and stand out for their beauty and mineralogical interest.


Size: 8.5 x 6.8 x 3.0 cm.
Main crystal: 18 x 16 mm.
