Excellent specimen from Herja mine, a world-class Romanian locality for stibnite. This piece is formed by numerous groups of divergent prismatic crystals, very brilliant and with visible terminal faces. Photographs do not do justice to the beauty of this specimen. Nowadays it is difficult to find samples of this fine quality. It belongs from a former Austrian collection.

Classic locality

Very rich group of sharp chalcocite crystals, some isolated and other interpenetrated, tabular and with very clear twinned pseudohexagonal forms. Intense metallic luster, gray color. They stand out on a matrix of bright calcite and small tennantite crystals. The specimens of this locality are very rare. Novelty in Sainte-Marie-aux-Mines 2017. The Mantos Cobrizos mine is a type of "mantle" deposit. This is a small Cu deposit, located in the mining district of Los Cóndores, close to Paipote, Copiapó. So far the production has been made a small scale.

The schorl specimens from Cap de Creus are well known to Spanish mineral collectors. This specimen from the 70s of the last century shows us a striated prism and defined facets of the terminal faces, something unusual. This area of the NE of Catalonia is now a Natural Park and it is totally forbidden to extract specimens.

Very brilliant specimen formed by various cerussite crystals, with a cyclic twin, well defined and translucent. They exhibit intense yellow fluorescence under LW-UV light. They are disposed on an upholstered matrix of small crystals of the same species and, to give an aesthetic touch, a group of orange baryte crystals.

Achtaragdite is a unique, rare and poorly understood pseudomorph, from this remote Siberian locality that is the Type Locality for grossular garnet. It is a variety of the grossular-hibschite garnet series and is (technically, according to mindat) a hydrogrossular-chlorite-carbonate pseudomorph after what was formerly considered to be wadalite or some other rare hydrogarnet. The real precursor mineral for these pseudomorphs is now considered to be helvite.

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.

A very aesthetic specimen from this classic Brazilian mine. Numerous aggregates of quartz crystals, with a very elongated prism, almost acicular, with well-defined terminal faces and exceptional luster and transparence. They form divergent aggregates on a siderite matrix, visible on the back, as lenticular crystals formed by flattened rhombohedra. Very aesthetic and huge size sample for this mine.

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.

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.
