A very curious specimen of calcite with deformed and curved escalenohedron and rhombohedron faces. With some brilliance, yellowish color and translucent. Very aerial disposed on a matrix of dolomite peppered with pyrite.

Group of interpenetrated fluorite crystals showing well defined faces, with delicate polysynthetic growth, and visible beveled edges. Good transparence and violet color with geometrical zoning. It presents the peculiarity of having a face that does not correspond to the predominant cube shape. On a quartz layered rocky matrix. A sample with characteristics that make it very interesting for fluorite collectors and from a classic Spanish locality.

A very rich pseudomalachite specimen, showing transparent lanceolated to elongated rhombohedra shape crystals. It is accompanied with a rare copper phosphate: reichenbachite. It shows globular aggregates formed by lamellar crystals with a lighter green color. They are disposed on a matrix of stalactitic goethite.

Group of isolated and very sharp metatorbernite crystals, with an intense green grass color, showing the combination of the first and the second order dipyramids, truncated by pinacoidal faces. Its intense color gives a nice contrast with the white quartz matrix. We could say that this locality is included in the most worldwide important torbernite localities due to the crystal quality, size and multiple habits.

Groups of very brilliant sphalerite crystals showing complex habitus and twins. With an intense luster and deep brown color, near black, with honey reflections. They are peppered by several small but brilliant chalcopyrite crystals. On a siderite matrix, accompanied by dolomite, galena and defined brilliant chalcopyrite crystals. Nowadays, this mine, in the city of Bilbao, is collapsed and it is impossible to get these classic Spanish specimens.

From a recent finding in an outcrop close to the Proserpina reservoir, near of the interesting city of Mérida (Badajoz). This specimen shows small turquoise crystals forming botryoidal aggregates with a nice bluish and greenish tones, partially covered by a second generation of more yellowish crystals. We'll send a copy of the analysis to the buyer. A Spanish novelty.

Group of fluorite crystal showing an elongated cubic prism, beveled on edges, with excellent violet color zoning. Directionally, they are partially covered with a layer of white quartz we wanted to preserve. They are very aerial disposed on a matrix covered by small but brilliant quartz crystals. They were extracted from la "coquera" (vug) called La Negrina (the black one), that appeared between March and April, 2006.

A very aesthetic and huge size group of calcite crystals showing rhombohedral forms, elongated along the main axis. Good definition, yellow color, due to the iron oxide coating. From a Spanish classic locality.

A very aesthetic group of calcite crystals showing rhombohedral forms, elongated along the main axis. Good definition, yellow color, with greater intensity at the acute forms, due to the iron oxide coating. From a Spanish classic locality.

Druse of very sharp fluorite crystals, with transparence and excellent yellow color. From a classic Spanish mine for the species.

A rich group of well-defined cubic crystals of fluorite showing polysynthetic growth on faces. Violet-purple color is very, very intense, with geometrical zoning in the crystal core. Many of them are interpenetrating, giving the whole a unique aesthetics. From a classic Asturian locality.

Curious specimen of calcite from Moscona. Formed by some crystals, one of them predominant, with complex rhombohedrall faces with echeloned growth. Accompanied by tabular barite crystals and on a yellow fluorite matrix.

Rich group of sharp isolated octahedral fluorite crystals, from translucent to transparent. They show an interesting apple green color. They are accompanied by small quartz crystals. On a granite matrix. This matrix is classic for modern specimens and comes from low levels of the Berta quarry.

A weakness, I admit. A cube-octahedral complex galena, defined edges, with polysynthetic growths on (111) faces. In one of them we can observe tiny crystals of pyrite and dolomite.
It comes from one of the classic mines of Catalonia: the Règia mine. In this mining area, occasionally, we could find small specimens but usually less defined. An opportunity to get a specimen from a classic Spanish locality.

Excellent and rich group of scalenohedral calcite crystals, with defined faces and edges. Some of them show the tips slightly reddish. They are very brilliant and translucent. Accompanied by shiny aggregates of tabular transparent barite crystals. A very showy specimen from a classic locality.

Group of octahedral crystals of galena, well defined, some vertices truncated by the cube. They are disposed on a brilliant matrix covered by twinned marcasite, small rhombohedral crystals of dolomite and sphalerite with a honey color and transparence.
A sample from a classic Spanish locality. Old specimen, so the stability can be ensured.

In this sample we have a complex twinned escalenohedron group, "doubly terminated", with combination with the rhombohedron. Transparence is excellent, with defined faces and delicate edges.
These specimens appeared accompanied by pink dolomite, at level 6 of this mine. An excellent miniature from this classic Spanish locality. Calcite specimens from la Florida mines are known and valued worldwide.

A very rich group of prismatic crystals of ferro-actinolite of intense green, near to black color, brilliant, defined, with flattened terminal faces and some with pyrite on them. Aesthetics is excellent and the vertical disposition of the crystals makes this piece a different sample.
They are disposed on a matrix of albite with several rounded and brilliant magnetite crystals. Also with small pyrite with complex and interesting forms. This specimen is an excellent representative for the species and more, if possible, for this Spanish locality.

On a rocky matrix of ophite we can enjoy several groups of fan-shaped epidote crystals. Intense green color and excellent brilliance. Prismatic crystals show flattened terminations. Acompanied by a layer of needle like actinolite crystals, fibrous and with a green bluish color. Specimens combining both species are uncommon because many times collectors clean specimens with water and eliminate this delicate formations. From a Catalan locality, a huge size and different aesthetics specimen.

In this double specimen we did not want to separate the two parts because symmetry gives them a very nice aesthetic touch. We can observe nodular aggregates of variscite. The green color is very intense. They are embedded in a type of silicified breccia matrix with iron oxides. Both are polished in the front side (which allows us enjoy the structures) and natural cut in the back side. To find samples of this quality you must go back to the past times.

In this double specimen we did not want to separate the two parts because symmetry gives them a very nice aesthetic touch. We can observe nodular aggregates and possible tigmatic folds in the veins of variscite. These meandering folds are caused by the flow of a viscous fluid into a more fluid media. The green color is very intense and it is combined with whitish and yellowish areas. They are embedded in a type of silicified breccia matrix. Polished in the front side (which allows us enjoy the structures) and natural cut in the back side. To find samples of this quality you must go back to the past times.

Specimen formed by nodular variscite aggregates showing concentric growths and intense apple green. They are embedded in a breccia matrix with limonite. It is polished on front side, necessary to enjoy structures, and natural on back side. To find specimens of this quality you must go back to the past.

Group of nodular variscite showing concentric growth and intense apple green color. They are embedded in kind of silicified breccia matrix. It is polished on front side, necessary to enjoy structures, and natural on back side. To find specimens of this quality you must go back to the past times.

Nice hemimorphite specimen from a classic Basque mine. Mineral is covering with a crystalline crust the cavities of the carbonated matrix. Color varies between blue, green to colorless.
