RM1957   Silver with galena and acanthite

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

In this specimen we can observe numerous skeletal growths of native silver, accompanied by octahedral crystals (with some cube faces) of acanthite and, very interesting, several cube octahedral galena crystals. These specimens come from the findings of the last years of the XXth century, being today very difficult to find them in the market and less with this quality.

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.
