Fragment of a sphalerite crystal, with complex faces and intense color when the light passes through it. Back side is exfoliated. From this classic locality.

Size: 5 x 3.8 x 1.5 cm.

Specimen with many years, from the Daunis collection (Barcelona), with the handwritten label. There are several groups of sphalerite crystals, brilliant, translucent with an intense orange color when the light passes through them. They are disposed on a matrix with dolomite crystals. The sample has not been treated, so it presents some areas with small scratches, typical of the time. A great sample from this classic Spanish mine.

Main crystal: 28 x 28 mm aggreg.
Found in ±1980.
