In this specimen we can enjoy several groups of wire silver, with showy wire to skeletal growths and metallic luster. Accompanied by black acanthite crystal aggregates. From a classic locality for the Catalan and Spanish mineralogy. A good chance to represent this locality in your collection. Nowadays it is very difficult find specimens, only from old collections...

The specimens of hematite from the Sandra quarry, where dolerites (ophites) are exploited, are known by local collectors, but those extracted in the Manzanera cemetery area have not been as abundant and of high quality. This specimen comes from the Marí-García collection (Castelló) and was collected in 2000. The hematite crystals form isolated "leaves" that are very shiny and iridescent, unlike the quarry. Very aesthetic and unique specimen.

Classic locality

Este ejemplar de fluorita de la cantera Berta nos muestra grupos de cristales pero también cristales aislados. La matriz es la granodiorita de color rojo "antigua" y se halla tapizada por diminutos octaedros de fluorita casi incoloros. Si algo hay que destacar de esta pieza es que los cristales octaédricos de fluorita muestran en los vértices las caras del rombododecaedro, del cubo y del tetraquishexaedro.

Size: 5.9 x 5.4 x 2.6 cm.
Main crystal: 8 mm.

Fluorescent under long wave UV

This specimen of fluorite from the Berta quarry shows us a group of crystals but also isolated crystals. The matrix is "old" red granodiorite and is lined by tiny, almost colorless fluorite octahedrons.

Size: 5 x 3.5 x 1.8 cm.
Main crystal: 9.5 mm.

This is a specimen of tabular barite crystals, colorless to yellowish tones and very good transparence. It belongs from the Mines d'Osor, currently closed and from which it is impossible to obtain these specimens. The mine closed in 1979 and had eleven levels, with a 290 meter deep shaft. You can still see the ruins of the old facilities and the well from which sphalerite, galena and fluorite were extracted and treated.

Size: 9 x 6 x 2.8 cm.
