A nice cobaltoan calcite specimen showing polished concretionary growths with a good and deep color and including white aragonite. The mineralization is filling fissures of the Triassic conglomerates, which are visible in this specimen. Main side shows a polished section where we can enjoy perfectly banded purple calcite and conglomerate individual clasts. Nowadays mine is partially collapsed and restored and it is impossible to get specimens.

A very rich group of sharp metatorbernite crystals showing tabular tetragonal forms, an intense green color and good luster. They show polysynthetic and echeloned growths, and also as isolated tabular crystals. We can observe a yellowish fluorescence due to the presence of metautunite. This species is visible also as yellowish tones in the core of some exfoliated crystals. A French mineralogy classic not seen since late 70's.

These specimens come from a mineralized vug found in 2009 from were were obtained several floating specimens and some with stalactitic shape. The walls of the fissure were covered by smoky quartz crystals. When samples are mined and pull out of the mine, a partially dehydratation occurs (from 12 to 8 H2O molecules) and torbernite become metatorbernite species. Margabal specimens can be classified as metatorbernite.

This elongated calcite crystal comes from the deposits of optical calcite of José María Patoni. These mining works are famous worldwide for the purity, transparence and crystallographic complexity of its calcite crystals. These specimens were formed by mineral rich hydrothermal fluids flowing through rhyolitic pyroclastic materials, where they found faults and fissures, a perfect place to grow.
This specimen shows faces of the prism, both scalenohedrons and rhombohedrons (positive and negative), echeloned faces and a small apical pinacoid. Excellent transparence and brilliance. A worlwide classic for calcite and crystallography.

Group of Galena crystals from an old mine in the area of Madan. This specimen shows well-developed cubic forms in staggered growth with defined edges and complex growths on faces. Its metallic luster has the original brightness of these original specimens and we decided to preserve. We would like to emphisize a group of very bright sphalerite crystals of intense honey color, near to black, showing tetrahedral forms and truncated  on vertices.

This is a sample of the first specimens collected from the area of Madan and belonged to a miner collection, with no more data.
