RM1956   Acanthite with Silver

Balcoll mine, Pozo 2 (shaft 2), Falset, Tarragona, Catalunya, Spain

Acanthite in the specimens of the Balcoll mine, usually appears in small crystals. In this piece there are several groups of acanthite crystals of good size, showing facets of the cube and the octahedron, some of them have grown on skeletal aggregates of native silver. Very interesting for the species and for this classic Catalan locality. These specimens come from the findings of the last years of XXth century, being today very difficult to find them in the market and less with this quality.


Size: 6.8 x 3.8 x 2.4 cm.
Main crystal: 5 mm.

RM985   Silver

Balcoll mine, Falset, Tarragona, Catalunya, Spain

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.


Size: 7.8 x 4.0 x 2.5 cm.
Found in ± 1999.

RM737   Silver with acanthite

Balcoll mine, Pou 2, Falset, Tarragona, Catalunya, Spain

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.
