Rosell Minerales

These specimens come from the rocky outcrops that are located near the town of Serveto. These are doleritic rocks in which epidote and these prehnites are found in. Currently it is very difficult to get samples. These specimens we offer date from the years 2005-2006. Prehnite appears as globular aggregates of prismatic crystals, sometimes more developed and visible. The light green color is very uniform. Rare locality not well represented in collections.

Size: 8.9 x 6.9 x 3.3 cm.
Found in ±2005-2006.

A very aesthetic example of this classic Romanian mine. Numerous aggregates of quartz crystals, with a very elongated prism, almost acicular, with well-defined terminal faces and exceptional luster and transparency. They form divergent aggregates on a siderite matrix, visible on the back, as lenticular crystals formed by flattened rhombohedra. Very curious and unusual for this mine.

Size: 8.4 x 7.3 x 6.5 cm.

Dalnegorsk fluorite specimens are very difficult to photograph. This is the case of this piece formed by groups of cubic crystals, transparent, colorless, defined, with the edges of the cube beveled by the dodecahedron and inclusions of very curious shapes. It is accompanied by quartz crystals dotted with green chlorite. A very curious piece ...

Numerous groups of prismatic willemite crystals in the cavities of this matrix with galena, siderite, quartz and goethite. The crystals show hexagonal shapes truncated by pinacoidal faces, they appear isolated or forming aesthetic stars. Some of them are dotted with rhombohedral crystals, between honey-colored to greenish, of siderite. Fluorescent under short wave UV light. A good size specimen of this classic Occitan Pb-Zn mine.

These pyrite specimens from this Bulgarian mining area are very aesthetic, highlighting the complex forms and penetration twins they present. Good luster and color. They are accompanied by crystals of quartz on the matrix. It comes from a mining area known as the Septemvri mine, which includes the following deposits: Sharenka, Baram, Mogilata, Osikovo and Pechinsko.

Size: 4.2 x 3.8 x 3.5 cm.

These baryte crystals are very different from the usual ones that we can see coming from this Moroccan locality and even from other deposits famous for baryte. These are prisms of different orders, the predominant third order, truncated by the second order. We observe that a white geometric growth has formed and only affects certain faces of the rhombic prisms. This zoning is unusual for the species. The crystals are transparent and brilliant.

Very rich chabazite-Ca specimen, with defined and brilliant crystals, those cover one side of the matrix, while on the other we can see numerous heulandite crystals with groups of chabazite-Ca in the upper part. This specimen belongs from the Faroe Islands (Færøerne, which means "islands of lambs"), an autonomous territory of the Kingdom of Denmark, made up of a small archipelago in the North Atlantic, between the United Kingdom, Norway and Iceland. It is not easy to find zeolites from this area.

Divergent aggregates of good sized acicular to prismatic goethite crystals. They are accompanied by black globular aggregates that, once analyzed, have turned out to be a first generation of goethite. It is accompanied by small aggregates of green conichalcite crusts, also analyzed. The specimen shows a fissure that has been consolidated, without affecting its stability and aesthetics.

Classic locality

These specimens show us a chalcopyrite matrix partially transformed into irisdecent covellite-bornite and goethite. In the cavities there are numerous aggregates of prismatic malachite crystals, of an intense green, with transparency and brilliance. If we observe them with the magnifying glass we can see that they are faceted crystals. A novelty in the Bleida mines area.
