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. We also observe some of them doubly terminated, highlighting one of them because of their size. 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. No damage. This sample is a nice representative of the known Llavorsí's quartz crystals.

On a barite matrix are disposed several brilliant and very sharp pyromorphite crystals with a very interesting deep olive-green color. They have grow in divergent directions. Some of the crystals are isolated, with an elongated prism. Very interesting under stereomicroscope, we can see excellent crystal growths. Really nice specimen. A classic between classics from this well known french mine closed in 1981. A great opportunity for pyromorphite and old classic mineral collectors.

On a quartz matrix are disposed some sharp pyromorphite crystals with a very interesting color zoning between light green in prism faces and yellow tones on terminal pinacoids. Crystals show a hexagonal barrel-shaped prism with flattened terminal faces on the top. They have grow in divergent directions. Some of the crystals are isolated, with an elongated prism. A classic between classics from this well known french mine closed in 1981. A nice specimen of pyromorphite.

On a barite matrix are disposed several sharp pyromorphite crystals with a very interesting color zoning between olive-green in prism faces and yellow tones on terminal ones. Crystals show a hexagonal barrel-shaped prism with the pyramid terminal faces on the top. They have grow in divergent directions. Some of the crystals are isolated, with an elongated prism. Contrasting with the dark brown matrix. A classic between classics from this well known french mine closed in 1981. A great opportunity for pyromorphite and old classic mineral collectors.

Tsumcorite is a rare lead, zinc and iron arsenate, with Type Locality in Tsumcorp mine (abbreviation of Tsumeb Corporation). This company worked this copper mine during many years, in the Tsumeb mining area. This specimen is very rich in intense orange-brown small crystals of tsumcorite. We can observe platy lanceolated tabular crystals. They are accompanied by mimetite globular aggregates partially covered by brilliant deep green duftite crystals. Huge size, great specimen and rare mineral, all combined. This specimen has been analyzed.

A very brilliant sulfur crystal disposed on a white dolomite and marble matrix. Well defined faces and edges, a little bit curved, good transparence and excellent classic yellow color. These specimens appear in vugs inside the Carrara marble quarries and it is not easy to get them without breaking them. An Italian gem.

Botryoidal aggregate of hydrozincite of white color, with yellow and bluish tones. We can observe different layer growths and radiated structures in fracture zones. It comes from a Basque very wide mining area not well represented, in this species, in collections.

Group of bluish fluorapatite crystals, showing well defined faces and edges. Some of them show defined prism and even hexagonal pyramid faces. Although the site is known, it is not easy to find samples on matrix with a good size and luster ... and on matrix, because it is very easy, when you work them, that crystals fall out. They are transparent to translucent with nice color zoning, more intense in the center of the prism. They are usually accompanied by quartz. In this sample we have a very nice crystal doubly terminated very aerial disposed on the quartz.

In this specimen we have a huge size crystal (8 mm) with prism faces, but not complete on terminal ones and smaller one (3 mm), defined and rich in faces.

On a matrix partially covered by quartz, isolated groups of cinnabar crysrtals; with an intense luster and deep red color. We note that some of them have interesting cyclic twins. One of them features that make this sample remarkable is the locality and the numerous crystals.

A really interesting specimen for its aesthetics, its locality and, of course, by the presence of this rare beryllium silicate, bertrandite. Specimen shows prismatic flattened crystals, well defined, forming rosettes. Perfectly disposed on a matrix of smoky quartz crystals and some brilliant pyrite.

Sold

Group of fluorite crystals with an intense luster, violet tones with color zoning more intense in the crystal core and geometric in faces. They show polysynthetic growths on faces that give them a particular shape. With some minor damages on some edges, but overall aesthetic. The sample is from an old German collection. A Spanish classic.

Group of very sharp interpenetrated fluorite crystals, with cubic faces showing echeloned forms. The violet-purple color is very intense, but when light passes through them it shows transparence and color zoning, intense in the external faces of the crystal and slight green tones inside. Good luster.
This specimen, that comes from an old German collection and was collected in the mid-80 in the mining area of ​​La Collada, is very distinctive and it isn't easy to see similar in the mineral market. Its color and disposition make it very atractive to fluorite collectors. A  former classic specimen from Asturias.

Brilliant fribrous aerinite aggregates, with a blue color with greenish tones. Usually aerinite from this classic locality is layering fissures in the dolerite rocky matrix. In this sample, the development of the fibers and its luster make it an excellent representative for the species. From a classic Spanish locality.

Group of very sharp cerussite crystals showing a reticulated growth, like a star or a snowflake, with good brilliance. Very aerial disposed. These specimens belong to a chance finding that yielded a few specimens of this quality. From the well-known mining area of Tharsis.

Druse of very sharp baryte crystals showing developed and striated prismatic faces, truncated by pinacoids. The crystals are translucent, and color varies between colorless to yellowish. Excellent brilliance. Similar specimens were classified, many years ago, as hokutolite (a lead-rich baryte variety) but further analysis showed that there was only a minor lead content.

A huge size native copper specimen showing an arborescent growth of deformed crystals. Some of them still show complex cubic forms. Its color is the original and I preferred not alter it by chemical methods. In some of the branches we can see the brilliance of copper, but the rest has this "coppery" tone.
Nowadays the mine is flooded, so get new specimens is quite complicate, if not impossible. A classic mineral specimen from this “Spanish pyrite belt” locality.

Its color is the original and I preferred not alter it by chemical methods. In some of the branches we can see the brilliance of copper, but the rest has this "coppery" tone. It is disposed very aerial on the rocky matrix.
