Epidote crystal, dark olive green in colour, very bright, with defined terminations, striking lighter green reflections and many flashes of greenish-yellow internal fire. Excellent specimen of Peruvian epidote.

Good size epidote crystal, dark olive green in colour, very bright, with defined terminations, striking lighter green reflections and many flashes of greenish-yellow internal fire. Excellent specimen of Peruvian epidote.

Size: 4.8 x 2.8 x 2.6 cm.

Very interesting galena crystal, remarkable for its crystallography. It presents the cube and octahedron faces with a very balanced proportion. Brilliant, well disposed on a matrix with quartz crystals with an elongated prism an some brilliant pyritohedrons. A Peruvian aesthetic especimen.

Size: 7.0 x 4.6 x 3.5 cm.
Main crystal: 18 x 16 mm.

This specimen shows several mineral species. The matrix which "supports" all of them is a group of huge size galena crystals with sharp cube-octahedral faces. Partially covering them we can see large groups of flattened realgar crystals. As alteration of these realgar crystals, due to the light, we have a patina, between yellow to orange, pararealgar. Between these galena crystals some orpiment aggregates, with a very intense yellow color.
We would like to emphisize in this specimen the presence of numerous seligmanite (PbCuAsS3) prismatic crystals, with a luster that makes them stand out. Evidently magnification is necessary to enjoy all their forms. Accompanied by chalcopyrite, pyrite and quartz. As you can see, it is a complete and representative specimen from this Peruvian mine.

Size: 7,5 x 6,0 x 5,5 cm.
