RM1957 Silver with galena and acanthite
Balcoll mine, Pozo 2 (shaft 2), Falset, Tarragona, Catalunya, SpainIn 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.
