In this specimen we can enjoy brilliant aggregates of brown transparent römerite crystals, a very rare iron sulphate. They are accompanied by coquimbite showing an intense violet color under fluorescent light or LED type. They're accompanied by numerous yellow metavoltine/copiapite crystals, along with minor fibrous halotrichite. Note that under the magnifying glass we can navigate in a world of brilliant crystals, some of which of krausite species (yellowish to grey transparent). We left this identification pleasure to the collector. Regarding its environmental stability, this sample has been stored during more than six years without further alteration.

Brilliant specimen of this Peruvian mine with a good size. It is a druse of quartz and calcite crystals, very bright and showing a bluish tone due to they are covering chrysocolla. Over them, we can see numerous groups of bright green clinoatacamite crystals. Well defined faces and edges, interpenetrating and isolated. A fine quality specimen, colorfull and with aesthetics.

Very sharp dipyramidal scheelite crystals those are coated by lemon yellow stolzite. They are disposed on a flattened hübnerite crystal partially covered by quartz crystals. Pure aethetic specimen.

Very sharp dipyramidal scheelite crystals those are coated by lemon yellow stolzite. They are on a matrix of quartz crystals. A very interesting and aethetic miniature.

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.

Very aesthetic divergent group of hübnerite crystals showing a marked prismatic habit, with good brightness, intense color, with very very visible reddish transparencies. They are disposed on a hyaline quartz matrix. A selected specimen.

Druse of brilliant hyaline quartz crystals, with transparence and well-developed prism. Some of them showing the Japan-law twin, flattened, transparent to translucent. From a classic Peruvian locality which was inaccurated located in Pasto Bueno district, Pallasca province.

Rich specimen formed by complex sphalerite and galena crystals partially covered by small but brilliant seligmannite associated with tetrahedrite, orpiment and quartz crystals. With pyrite and chalcopyrite. You can see under magnification very aesthetic orpiment-seligmannite aggregates. A very nice combination.

Druse formed by rhombohedral crystals of very well defined faces and edges and excellent, very intense pink color. Some of the crystals are partially covered by small quartz crystals.

A very aesthetic fluorite crystal, greenish to bluish tone with zoning, transparent and brilliant. It shows cube faces modified by the trapezohedron. With small pyrite crystals. Very aerial disposed on a brilliant and defined hyaline quartz crystal.

A rich group of fluorite crystals, greenish to bluish tone, transparent and brilliant. They show the cube faces modified by the trapezohedron. With small pyrite crystals. Very aesthetically disposed on a brilliant and defined hyaline quartz crystal.

A very aesthetic group of deep green crystals of epidote. Fan-shaped thick prismatic crystals with well defined terminal faces. Just a very few of the terminations are incomplete. Good brilliance and very aerial.

Brilliant specimen formed by globular aggregates of orpiment crystals, with good orange-yellow color. They are accompanied by brilliant acicular crystals of realgar with deep red color, transparent and defined. It is accompanied by barite crystals, pyrite and pyrrhotite. A different and quality specimen for this classic Peruvian mine.

A very nice specimen with an intense green globular aggregate of malachite partially covered with quartz, perfectly disposed on a matrix of brilliant quartz crystals and chrysocolla. Excellent brilliance and good aesthetics.

Good sized specimen that shows large groups of clinoatacamite crystals with pseudorhombohedral shape, with intense green color, brilliance and transparence. They are disposed as isolated individuals those stand on a matrix of small but brilliant quartz crystals, with blue tones of the chrysocolla, green for the malachite and with gypsum. A remarkable and definitive piece from this Peruvian mine.

In this specimen we can find two of the most interesting species of this Peruvian mine: clinoatacamite and atacamite. The first one is presented as pseudorhombohedral good sixed crystals, with an intense green color and translucent. Well defined faces and edges and isolated, allowing to observe them perfectly. The atacamite is presented as a tabular prismatic crystal, also with faces and sharp edges and bright green color. Matrix is covered by brilliant quartz crystals which transparence allow us to see green tones of the malachite.

This good size specimen is covered by botryoidal aggregates of chrysocolla, showing an intense blue turquoise, with greenish reflections and excellent brightness. On the crisocola we can observe small crystals of hyaline quartz, some doubly terminated, those give to the specimen a particular aesthetics. In Perú they named these samples as Blue Andean Opal.

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.
