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 silver specimens from this classic German mine has been known for a long time, but in these specimens silver is included in chrysocolla, of an intense greenish blue colour, and shows a remarkable luster, sometimes with golden iridescence. Under magnification we can see facets of crystals of this metal. We have analyzed these samples and the results indicate that they do not contain other metals detectable by SEM-EDS. These specimens are already a few years old.

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.
