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...

In this specimen we can enjoy several groups of wire silver formed by small but brilliant crystals. They show skeletal and arborescent growth, with an excellent metallic luster. Accompanied by black acanthite aggregates but some of them very brilliant, curious. From a classic locality for the Catalan and Spanish mineralogy. A good chance to represent this locality in your collection. Last specimens.

A very aesthetic specimen formed by a large group of silver crystals and filaments, forming spongy and skeletal growths. Good luster and a slightly tan tone. Stresses this specimen by several factors. One is its size and weight (on 40 g. or 1.4 oz.). Another is the abundance of this noble metal and perhaps the most interesting is that it is not an acidified sample. This is a plate obtained from a natural fissure in the host rock, with a lenticular and flattened structure. A very different piece from this classic Catalan locality.

This specimen shows one way how silver occurs in Balcoll mine. We note that into the fissures in the limestone have grown numerous skeletal aggregates formed by silver crystals showing well defined forms of the octahedron. Good luster and a bronze patina tone. Accompanied by groups of cubic crystals of acanthite with staggered growths and deep black color. A very representative sample from a classic locality for the Catalan mineralogy.

A very aesthetic specimen formed by several groups of cubic silver crystals with a skeletal shape. They show defined octahedral and cubic faces. The color varies from white to bronze. Accompanied by acanthite aggregates with a darker color. These specimens come from a classic Catalan locality for the species.

A very rich specimen of silver from a classic locality for the Catalan mineralogy. In this sample we could enjoy several groups of very sharp brilliant skeletal silver crystals. They are accompanied by acanthite aggregates of darker color. The specimen has been acidified with care since usually silver specimens become dark, but in this case, and looking at the date of collection, we can foresee a long stability. The label indicates that this material was mined in 1905, but the specimen was collected in 1998.
