A very sharp emerald crystal "trapped" between calcite crystals. The color, transparence and brilliance of these crystal are more than excellent. It shows a very defined prism, with a perfect top pinacoidal face and hints faces of the dipyramid, observed between the prism and the pinacoid. Some interesting color zoning can be observed in its lower part. A true gemmy miniature.

A gemmy emerald crystal with an intense color, disposed very aerial on a matrix with calcite and small crystals of the same mineral. It shows a developed prism, with curious growths on faces, and a terminal pinacoid showing natural corrosion forms and a small dent, which does not affect its aesthetics. Good transparence and brilliance. Good choice with an excellent price.

Group of very nice elbaite crystals, one of them with a good size, transparence and marked color zoning. They are accompanied by a rich group of clevelandite crystals very aerial disposed. We can observe groups of developed lepidolite crystals those give an aesthetic touch to the specimen.

Group of divergent elbaite crystals with good brilliance, defined prismatic faces and complex terminals, almost needle. Good transparence that reveals green color, violet at the upper terminal faces and a delicate red tone in the crystal core. The color zoning is very marked. A gemmy specimen.

A huge size specimen formed by a large group of brilliant pentadodecahedron pyrite crystals. With an excellent luster, gold color and very well defined faces and edges. On a solid matrix of hematite crystals. A specimen for the best display.

A very curious aquamarine crystal showing a well developed prism and a very interesting termination, not very common for the species. We can see at the top, the sharp faces of the dipyramid. On this terminal faces have grown another crystals finishing on the top by a dipyramid truncated by the pinacoid. It has a slight bluish tone. Transparence and brilliance are very good. It is very vertically disposed on albite crystals matrix. A crystallographic gemmy specimen.

Group of cubic fluorite crystals showing well defined faces and edges, with echeloned polysynthetic growth. Excellent transparence and blue to colorless depending on light source. On a quartz layered rocky matrix. A sample with characteristics that make it very interesting for fluorite collectors and from a classic Spanish locality.

Group of cubic fluorite crystals those show defined faces and edges with very interesting staggered polycrystalline growths. Its color varies from bluish violet to purple depending on the type of incident light. Good transparency showing us some color zoning. An aesthetic specimen from a classic Asturian locality.

On a milky quartz matrix we can enjoy some cubic fluorite crystals. One notable for its size. It shows transparency and color zoning. This color zoning is very interesting because it takes the form of an octahedron with an intense violet included in a colorless cube. It is not easy to find samples of fluorite from Cerro Muriano; so even a small dent in a corner, this piece is great quality for the locality.

This specimen shows stalactític aggregates of rhodochrosite with a pink color. They are accompanied by brilliant botryoidal kentrolite, with a deep black color. It is a rare lead and manganese silicate. Nice specimen for the species and dedicated to systematic and French collectors.

This specimen shows parallel growths on a single axis, so typical of the finds from N'Chwanning mine. The tetrahedral crystals are brilliant with very well defined faces and edges and showing echeloned and skeletal growths. Good size for species.

Very aesthetic group of aerial malachite crystals pseudomorphic after azurite showing a tabular shape with rounded faces. Color is deep green with a very well marked velvet luster. Good specimen from Milpillas.

Large group of cubic fluorite crystals showing well defined faces and edges. The yellow honey color, brilliance and transparency of the crystals give a very aesthetic touch to this piece. Viewed under magnification they are peppered by small globular aggregates of pyrite. It is accompanied by white dolomite.

In this specimen we have a very curious combination of erythrite forms. On the one hand, globular aggregates of this arsenate formed by needle like crystals with a velvet luster and a pale pink color. On the other hand, groups of lanceolated crystals with defined faces and edges, good transparence and deep purple color. All of them are disposed on a matrix with sharp cube octahedron skutterudite crystals. A fine specimen for this Moroccan locality.

A brilliant and very sharp bixbyite crystal. A manganese oxyde well-known and appreciated by collector for its rich crystallographic forms. In this specimen we can see the cubic main form with vertex truncated by trapezohedron and a small triangular octahedron face. A crystallographic pleasure... Very aesthetically disposed on a volcanic rocky matrix. With an old display label.

Very curious group of interpenetrated leucite crystals pseudomorphosed by feldspar. A classic from Czech Republic appreciated by pseudomorph collectors. Good size.

Brilliant and elongated gold nugget that suggests rounded and flattened subhedric crystals. It belongs from an area known till the middle of last decade for its gold nuggets. The sample shows a good size. An opportunity to add a Spanish gold to your collection. Weight: 3.49 g. / 0,1231 oz.

Brilliant gold nugget that suggests rounded subhedric crystals and a surface with concavities. It presents quartz granules as inclusion. It belongs from an area known till the middle of last decade for its gold nuggets. The sample shows a good size. An opportunity to add a Spanish gold to your collection. Weight: 2.99 g. / 0,1055 oz.

A huge size specimen showing botryoidal aggregates of rosasite, with a velvet appearance and intense blue-green pastel tones. They are peppered with small but brilliant calcite crystals with a pseudooctahedron shape. On a limonite matrix.

Excellent group of doubly terminated aquamarine crystals showing a well developed prism and a very interesting terminal faces: the first order dipyramid truncated by the pinacoid. It has a slight bluish tone, near colorless. Transparence and brilliance are very good. With some unknown reddish inclusions (rutile?). Accompanied by some aquamarine doubly terminated crystals, albite-feldspar, dravite and colorless fluorapatite (between two V beryl crystals, see photo). A gemmy specimen.

A specimen formed by some tetrahedrite crystals of very good size. They show faces of the positive and negative tetrahedron, very sharp and rich in faces. Some of them are coated with a thin golden patina of chalcopyrite, a very aesthetic rarity. They are accompanied by bright calcite that partially cover with a geometrical disposition. A specimen of great aesthetic and interesting by the size of its crystals.

Mamellonar aggregates of smithsonite crystals with a very nice orange to brown color covering cavities in the rocky matrix. From a recent find (2014, april) in one of the biggest "cortas" (quarry) of Portmán mining area.

A curiosity that I found aesthetic and mineralogically interesting. Usually the menilite opals are found in a marlstone matrix, but in this case we found it included in gypsum with clay inclusions. A Spanish curious specimen...

Group of lenticular calcite crystals, very transparent and brilliant, with an uncommon shape for the species due to the flattened hexagonal shape. Disposed very aerial on the limonite matrix with hemimorphite.
