NE56L6

Parallel growth of idiomorphic Barite crystals, one of them dominant, with excellent transparency and brilliance. Their upper and side faces have very well marked triangular growth figures that give the edges a sawtooth appearance. Also we can see corrosion and contact geometric structures on some faces. We call your attention to the interesting Chalcopyrite crystal inclusions, where the original yellow greenish color is preserved, while superficial crystals on Barite faces are covered by a thin oxidation layer. The specimen is from mining works of Aizpea, close to the La Troya Mine.

NV8L6

Very esthetic Quartz crystal, with very sharp faces and edges. Intense and uniform smoky color and good transparency. Prism faces present fine horizontal striations. On a small Albite matrix. A small gem. Actually it is quite difficult to obtain high quality specimens from Massabé Quarry.

NE9L6

Multiple crystal growth of Amethyst crystals showing short prisms. Very sharp faces and edges, with great luster. Really good and uniform color, more intense at the top of the pyramids, grayish color in prism faces. This specimen is from the AVE (Spanish High Speed Train) quarry works where actually it is quite impossible to obtain quality specimens.

NA10L6

Parallel growth of Amethyst crystals, with a second generation of small Quartz crystals, some of them doubly terminated, which grew perpendicular to the specimen main axis. Color is more intense in terminations. A very curious specimen for the locality. This specimen is from the AVE (Spanish High Speed Train) quarry works where actually it is quite impossible to obtain quality specimens.

N8CL6

Nice miniature formed by complex crystals of Sphalerite, with well defined faces and edges, excellent luster and deep honey color. This mine closed a long time ago, and is now flooded and collapsed. Actually it is quite impossible to obtain specimens there.

N58DL6

Druse of Sphalerite crystals with very sharp faces and edges, some of them with curvatures. Excellent luster and deep honey color. On the back side, one can see very bright lenticular Calcite crystals, accompanied by yellowish Dolomite and Pyrite. This mine closed a long time ago, and us now flooded and collapsed. It is quite impossible to obtain specimens there.

N9APL6

Group of Sphalerite crystals with well defined faces and edges, some of them with curvatures. Excellent luster and deep honey color. Sphalerite contrasts with the yellow to orange Dolomite crystals matrix. Accompanied by Pyrite and Marcasite. This mine closed a long time ago, and it is now flooded and collapsed, so it is quite impossible to obtain specimens there.

N60GL6

On a snowy white Dolomite crystal matrix, some of which is in the form of the so-called saddle-shaped crystals, groups of Sphalerite crystals with excellent luster, transparency and deep honey color. This mine closed a long time ago, and it is now flooded and collapsed, so it is quite impossible to obtain specimens there.

N12FL6

Group of complex Sphalerite crystals with well defined faces and edges, some of them with curvatures. Excellent luster and deep honey color. On a Dolomite matrix, with olive green Siderite. This mine closed a long time ago, and it is now flooded and collapsed, so it is quite impossible to obtain specimens there.

N13AHL6

Sphalerite crystals with well defined faces and edges, some of them with curvatures, with good honey color. Most are peppered by small Pyrite crystals. On a matrix with Siderite and Pyrite crystals. This mine closed a long time ago, and it is now flooded and collapsed, so it is quite impossible to obtain specimens there.

N11BL6

Group of Sphalerite crystals with well defined faces and edges, some of them with curvatures, on a white Barite matrix formed by tabular crystals, some of them with a good size. An uncommon mineral association for this mine, that closed long time ago. It is flooded and collapsed, and so it is quite impossible to obtain specimens there.

N8BL6

From a not so well known area at La Pesquera, North of Minglanilla (Cuenca), we present this curious doubly terminated Aragonite specimen that shows on prism faces brownish and violet tones. Probably the most interesting thing are the delicate fibrous terminations on both sides and its good size. For specialized collectors.

N57AL6

From the last mining works that tried to exploit again the Quarries in Lumbrales, we offer this Quartz crystal with sharp faces and edges, milky color on the upper prism and pyramid due to a second phase of recrystallization, showing its original transparency in the middle of the prism. At the bottom we can see Cassiterite, the classic mineral from this locality.

N9BL6

From the last mining works that tried to exploit again the Quarries in Lumbrales, a very interesting Quartz crystal with sharp faces and edges, and a slight and uniform smoky tone at the top, milky at the base. One can see some geometric hoppered growth forms. With Orthoclase and kaolinized Mica.

L58RL6

A large Beryl (var. Emerald) with intense color. The specimen preserves the hexagonal shape, with curved faces partially covered by Muscovite as a matrix. From the most classic Spanish locality for Emerald, although nowadays it is quite impossible to obtain specimens there.
