A very rich specimen of cuprian adamite, formed by several very sharp pseudooctaedral crystals, with an excellent brilliance and transparence. Color is different than usual for the species and mine, with a green to bluish tones. Adamite crystals are partially covering a vug in the goethite matrix. A display huge size specimen and a very good aesthetics. From this classic classic Mexican mine.

Groups of tabular wulfenite crystals of intense orange color, showing parallel growth. If anything distinguishes these wulfenite crystals is its vivid color. The brilliance is excellent and in thin areas show transparence. Disposed very aerial and accompanied by fan-shaped barite crystals.

This specimen was collected a few days before our visit to the mine. A group of vanadinite crystals with a hexagonal shape and forming nice globular aggregates. The color is orange to reddish, with good transparency and disposed on vugs in the compact limonite matrix, covered by small goethite lenticular crystals. A not very common specimen from this classic mine.

One of the specimens with a exceptional color, excellent brilliance, a real gem. Very rich group of vanadinite crystals showing a defined hexagonal shape, with very well defined faces and edges, intense red color. Good brilliance and some transparence, with internal reflections between red and orange. Main crystals size are remarkable. Covering the barite matrix. The presence of this barite matrix is highly appreciated by collectors.

This sample was collected from one of these shafts where berber (amazigh) miners are working hard during months till they found a vug. This extended area, called Coud'a (Coudia), is located about half mile from well known ACF mine, but it is not the same mine. The vanadinite veins mined in Coud'a, which are approximately 30 to 50 feet deep, are not the same than ACF mine and their particular mineralogy.

Excelent group of vanadinite crystals showing a defined hexagonal shape, with very well defined faces and edges, intense red color. Good brilliance and some transparence, with internal reflections between red and orange. Main crystal size and thickness are remarkable. They are disposed very aerial and isolated on a lenticular barite crystal matrix. The presence of this barite matrix is highly appreciated by collectors and gives to the specimen a special aesthetics.

The large mine of Les O is mined under the town of Mibladen. It has been worked during generations of miners in search of specimens, usually galena cerussite, barite and some wulfenite. Few weeks before my visit in February 2013 were found some mineralized veins and vugs with the specimens we offer. When those cavities were formed they had been filled by cube octahedral crystals of galena and barite. Due to the hydrothermal fluids galena was partially or totally corroded to favor the formation of cerussite.

In this specimen we observe groups of tabular lenticular aggregates of barite with a delicate reddish tones, along with gray galena that has been almost completely substituted and covered by nice cerussite crystals. Taking a look under the microscope, cerussite shows long striated prisms terminated by pyramidal faces. Also note several cyclic twins, well defined and spectacular. Different specimens from Mibladen.

In this specimen we can observe some groups of tabular wulfenite crystals of  intense, very intense orange color, showing defined faces and parallel growth. If anything distinguishes these wulfenite crystals is its vivid color. The brilliance is excellent and in thin areas show transparence. Some of the dominant crystals are disposed very aerial and accompanied by groups of barite crystals. If you observe closely the specimen under the microscope you will see numerous perfect tabular crystals of wulfenite. Very aesthetic specimen.

In this specimen we can observe some groups of native copper crystals, with defined faces and edges, good luster and color. They are disposed on a black layer of pyrolusite and accompanied by some white to translucent calcite flattened rhombohedral crystals. These specimens were collected in a concrete areas of this mine.

Druse of divergent prismatic cobaltoan calcite crystals showing rhombohedral terminal faces, which is not usual, perfectly defined and with good brilliance and translucent. The color varies between pink and tile red . Some of these crystals are partially covered on prism by small and brilliant minute calcite. This color zoning can be seen in the fractured area of the sample. From a Moroccan classic locality.

Although our country is rich in different forms of calcite, we want to emphasize on this specimen that shows two generations of crystal growth. The first generation calcite clusters have a good size and orange to yellowish pastel tones. With an elongated striated prism and rhombohedral terminal top forms. They are translucent and brilliant, with echeloned growths on faces.
A second generation of small, but transparent and brilliant calcite crystals, is disposed near to perpendicular on the prism of the first generation. A colored and strongly fluorescent calcite from la Cala.

Calcite specimens from la Florida mines are known and valued worldwide. In this sample we have a complex twinned escalenohedron, "doubly terminated", with combination with the rhombohedron. Transparence is excellent, with defined striated faces and delicate edges. It has a delicate yellow to orange tone. In this specimen we can see, in the rear, the contact with the dolomite matrix where crystal had growth and an exfoliation, that does not affect the aesthetics of the sample.
These specimens appeared accompanied by pink dolomite, at level 6 of this mine. On one side there is a hoppered cavity in which it was disposed another group of crystals. A huge size and excellent specimen from this classic Spanish locality.

A very rich group of fluorite crystals with a good size and defined faces and rounded beveled edges. The faces show polysynthetic growths those give it a curious echelonesd forms and accompanied by complex redissolution structures. Really interesting. The color is intensely violet, deep in the inner parts of the crystal and clearer in the outer ones. Good brilliance and transparence when the light strikes on them. A specimen of the past times, rarely seen nowadays. It belonged to an old German collection. Col. Nr. 7.

On a heavy Co-As primary minerals matrix are disposed a rich group of acicular prismatic erythrite crystals. They form the usual globular aggregates but, in this specimen, disposition and this pink to orange color give to the specimen a different touch. A classic from this Moroccan cobalt locality.

On a rich Co-As primary minerals matrix are disposed several groups of acicular crystals of erythrite forming colloquially called: hedgehog aggregates. They are partially covering the matrix, as isolated groups or like a velvet. The pink to fuchsia colors are remarkable and confers to the specimen an excellent aesthetics.

Group of very sharp fluorite crystals from this classic of the Spanish mineralogy. We can see the cube forms, with defined edges and faces. With clear geometric color zoning, between purple to violet depending on the incident light, more intense in the crystal core. A specimen of fluorite which collector should not miss.

An excellent sample of a calcite showing a marked butterfly twin. Two twinned crystals in the same sample. Good transparence and very aerial disposed. This calcite comes from the deposits of optical calcite of José María Patoni. These mining works are famous worldwide for the purity, transparence and crystallographic complexity of its calcite crystals. Nice miniature.

Scolecite and aerinite specimens from this small Aragonese town are known worldwide. This specimen shows groups of acicular prismatic crystals those form globular aggregates which, when extracted, they allow us to see the radiated growths perfectly. Snowy white color and good luster. Samples of this quality are rare and less nowaday. Usually radiated aggregates appear very flat filling cavities into the dolerite rock.

Group of very sharp adamite crystals showing an intense brilliance and color between yellow to colorless. Different orders prisms are present, isome of the end faces can remind the octahedron. Thus, in the specimen we can see very elongated crystals, some other flattened and almost equidimensional. Transparence and luster are really good. Crystals are disposed very aerial on a goethite matrix. This sample belongs to a German collection.

It is a brilliant smithsonite specimen from a mine not well represented and very uncommon in the collections, including the American collections. These zinc carbonate crystals show a polysynthetic growths of rhombohedrons, color between white to colorless, with a strong pearlescent luster and forming botryoidal aggregates. They are accompanied by blue-green rosasite, in spherical aggregates.
This specimen is interesting for different reasons. The accompanying old label belongs to the Antigua Casa (former house) Soler Pujol of Barcelona, ​​known for its collections relating to the natural history sciences. We add to its history that this specimen was in the collection of Mr. Lluís Daunis, also from Barcelona. An old specimen from a interesting American locality.

Group of strontianite crystals with an elongated pyramidal habit, forming bundles and aggregates, with color between white to colorless. These specimens appeared in a concrete area of the mine Oriolana (Busot, Alicante) and initially were identified as aragonite or calcite. Further analysis indicated that this was strontianite with some calcium. It indicates that the crystals are zoned and its composition varies within the crystal. They were determined strontianita (majority), celestite, calcite with some quartz (probably due to mechanical mixtures). 

A very rich group of sharp psedo-octahedrical scheelite crystals, with an intense brown color, excellent luster and some transparence. They are disposed on a quartz matrix partially covered by small clinochlore green crystals. A very nice specimen for display.

A very rich group of quartz crystals, some of them doubly terminated, with well defined faces and edges. Interesting elongated prism and terminal faces. We would like to emphisize the delicate filamentous inclusions that can be seen inside through transparency.
These inclusions are of unknown composition, but probably due to fluid inclusions originated during the crystal growth. They are accompanied by curious hemispherical aggregates of goethite-limonite, with a intense orange color, formed after the quartz crystals. From a known mining area, but these specimens are not well represented in collections.

A brilliant quartz crystals from a well known Catalan area, in the Pyrenees, very appreciated for the quality of its hyaline crystals. A rich group of quartz crystals showing a elongated prism and developed and deformed rhombohedral terminal faces. Transparence and brilliance are excellent, with very well defined faces and edges. They are partially covered by small aggregates of pyrophyllite, between colorless to slightly yellow, with some goethitized pyrite. These specimens usually occur in geodes and it is very common find them falled down inside the vug; this specimen shows that one of the crystals has been lost, without affecting the beauty of the whole. This huge size sample is a nice representative of the known Llavorsí's quartz crystals.
