These crystals show astonishing sharpness of tetrahexahedron faces, together with the less developed cube. Crystals are uncolored (under halogen light) or slightly bluish (under fluorescent light), bright and completely clear and are scattered over an esthetic matrix of white crystals of barite. A high-quality specimen that belonged to the Silvane (Barcelona) collection.

Size: 6,6 x 5,5 x 2,7 cm.
Main crystal: 9 x 8 mm.
Found in 1995.

Ex-col. Silvane (Sr. Amigó).
Fluorescent under LW-UV and SW-UV lights

A very rich group of pyrite crystals forming a globular aggregate, very brilliant, with an intense color and hinting cubic faces. It is disposed very aerial on the matrix with rhombohedral calcite crystals and yellow fluorite. To increase its aesthetics a single calcite crystal has grown on the pyrite. A unusual specimen for this mine where pyrite is often found in small crystals coating the fluorite.

Size: 11,0 x 7,3 x 6,5 cm.
Main crystal: 3,7 x 3,0 cm (aggr).

A very rich group of interpenetrated fluorite crystals with cubic forms with beveled edges by the dodecahedron. Very sharp and with a really intense color, that varies depending on the incident light, between blue-violet to purple. A high quality Spanish fluorite specimen, from my own collection.

Size: 5,0 x 4,7 x 3,5 cm.
Main crystal: 12 x 11 mm.

Group of very sharp fluorite crystals with good transparence and brilliance, with a bluish color, well disposed very aerial on a barite matrix. We would like to emphisize the size of the main crystal and its good definition, showing perfectly tetrahexahedron faces with an interesting slight curvature. A classic from Asturies.

Size: 6,0 x 4,2 x 4,0 cm.
Main crystal: 24 x 23 mm.
Found in 2005.

Fluorescent under long wave UV

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.

Size: 4,8 x 3,8 x 3,8 cm.
Main crystal: 23 x 23 mm.
