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.

Fluorescent under LW-UV and SW-UV lights

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.

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.
