RM2603   Silver

Aït Ahmane (filon 53), Agdz Cercle, Zagora, Drâa-Tafilalet, Morocco

This specimen stands out for showing arborescent growths of very well defined silver cubic crystals. In addition, the piece comes from a Moroccan mine from which few samples of this type and quality have been collected. To add more importance to the piece, it must be said that the calcite has been partially removed by mechanical procedures, without acids that could cause the silver to blacken. Well defined, extremely brilliant and isolated silver crystals are not very common, usually appear deformed or in complex growths. An excellent and good sized specimen.

RM2602   Römerite with coquimbite, krausite...

Javier Ortega Mine, Huachuas, Lucanas, Ayacucho, Peru

In this specimen we can observe brilliant aggregates of brown transparent römerite crystals, a very rare iron sulphate. They are accompanied by coquimbite showing an intense violet color under fluorescent light or LED type. They're accompanied by yellow metavoltine/copiapite crystals, along with minor fibrous halotrichite. Note that under the magnifying glass we can navigate in a world of brilliant crystals, some of which of krausite species (yellowish to grey transparent). We left this identification pleasure to the collector. Regarding its environmental stability, this sample has been stored during more than eight years without further alteration.

RM2583   Doubly terminated quartz

Serrabal mine, Vedra, A Coruña, Galícia, Spain

Group of doubly terminated quartz crystals, with developed prisms and defined terminal faces, translucent. With interesting parallel growths. These specimens were collected in this A Coruña quarry that exploits quartz, one of the main mines in the world due to the quality and quantity of its reserves. The mine was discovered in 1968 by three Galicians who gave their name (from their surnames SEñarís, RAma and BALboa) to the concession and who found it while exploring these mountains in the Pico Sacro area in search of "seixo" (from the Galician: hard white rock) of good quality.
