Superb specimen of fluorite from the mythic vein called Josefa-Veneros. A druse of fluorite crystals showing the cube faces with beveled edges by the dodecahedron. Good brilliance and intense violet color with zoning, more intense on edges. The definition of faces and edges is excellent and the crystal size more than interesting. An opportunity to get a classic from Asturian fluorite, not easy (near impossible) to be found nowadays.

These specimens have given more than a headache. They have sometimes been cited as celestine from Moscona mine. This specimen shows a group of barite prismatic crystals very rich in faces, with the combination of various orthorhombic prisms and pinacoids. Transparency is excellent and with an amazing brilliance. They are disposed in a matrix with white crystals of calcite. Very few specimens in collections.

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.
