Quartz specimen with marked "window" growths with inclusions. These Allos pass crystals are not very common on the market. Allos pass is situated on the edge of Mercantour National Park approximately 20 km from the small village of Barcelonnette.

Group of octahedral pyrite crystals, very brilliant and well defined, which are accompanied by complex crystals of sphalerite. On them we observed numerous white globular crandallite aggregates (analyzed by XRD). This combination of minerals is unusual in the deposit, with this phosphate being the first citation.

Very thick and good size stibnite crystal from this classic Romanian mine. It presents an elongated prism, striated, with an excellent brightness. Very rich in facets in the upper terminal part, with complex bipyramidal faces. On the main crystal we observe a group of crystals of the same mineral, finer, that suppose a second crystallization. Nowadays it is difficult to find specimens of this quality from this mine. It comes from a former Austrian collection.

More than an excellent specimen from Herja mine, a world-class Romanian locality for stibnite. This piece, of a very good size, is formed by several groups of thick prismatic crystals with visible terminal faces. We can observe a second generation of thin crystals. Nowadays it is difficult to find samples of this quality, for museum display cases. It belongs from a former Austrian collection.

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.

Esthetic specimen formed by groups of lepidolite mica, bright and defined, on which we observe see a brilliant topaz crystal, slightly bluish and faceted, with excellent transparency. Uncommon on matrix. With old handwritten label.

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.

Excellent specimen of galena, with very good luster. It shows forms of the cube and the octahedron, twinned. It has very aesthetic skeletal and ochy growths. The mine produced specimens of this quality a few years ago and now it is increasingly difficult to find them.

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 aesthetic aggregates of epidote crystals forming beams, with brilliance, defined and with this classic green color. They are disposed on the matrix with quartz crystals, forming very interesting concentric growths.

Very aesthetic aggregates of epidote crystals forming beams, with brilliance, defined and with a classic green color. They are arranged in groups and in an isolated way on the matrix with quartz crystals, on which they stand out.

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.

Group of cubic to prismatic fluorite crystals, translucent, with a color between violet to purple depending on the incident light. A good size specimen with a matrix on the back. From this classic Moroccan mine.

A novelty from the Bleida mines. Groups of malachite crystals, prismatic to needle like, forming velvety aggregates with intense brilliance and color. They are disposed in the cavities of a quartz and dolomite matrix, with cuprite.

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, sphalerite and brilliant chalcopyrite 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.

This group of hyaline quartz crystals belongs from the Cabiche mine, very sharp, with exceptional transparency and luster. They show parallel and at the same time crossed growths. Quartz specimens from this Colombian mine, located in the Boyacá emerald mining area, have been well known since the end of the last century.

Quartz specimens from this Colombian mine, located in the Boyacá emerald mining area, have been well known since the end of the last century. By 2017, new galleries were opened those located different geodes. These crystals, called "mango quartz" or "crown quartz" were found in them, with inclusions that, after being recently analyzed, were determined as halloysite. The inclusions show filamentous structures and the tips of the crystals turn to orange tones. On our website we have already sold some samples with these inclusions on sale, without the orange coloration. Really aesthetic and on a matrix with goethitized dolomite-siderite.

Brilliant specimen formed by a druse of defined tarpezohedral crystals of grossular, hessonite variety. Intense color, shine and transparence. It is accompanied by groups of green clinochlorine crystals.

Elongated cubic fluorite crystal of very good size, with tile growths on the faces. Between translucent to transparent and with a very uniform violet color. It is complete on both sides and is placed on a small matrix with quartz.
