A very rich sample formed by groups of butterscotch tabular thick wulfenite crystals to 9 mm on edge. NIce color, luster and defined faces and edges. This specimen is from an old German collection.
The mine has been exploited for over three centuries. The Miess lead-zinc deposits is one of the richest in Europe. The district has produced the most excellent wulfenite specimens of Europe.
A very aesthetic group of stalactitic goethite-hematite growth showing a very aerial disposition from this classic Moroccan locality. We can observe reddish radiated growths in fractured stalactites on the matrix.
On a matrix formed by corroded quartz crystals, due to chemically aggressive media, are disposed several small pyromorphite crystals of hexagonal prismatic habit, with a extraordinary brilliance, transparence and definition. In addition, its color, almost yellow-green near fluorescent, adds a special touch to this sample. The Daoping Mine has produced a large variety of pyromorphite since ca. 2000 and this is a particular example.
Cobaltoan calcite specimen showing carbonate growths with colours between magenta and yellow, typical for this classic Catalan mine. The mineralization is filling fissures of the Triassic conglomerates. Nowadays mine is partially collapsed and restored and it is impossible to get specimens. This sample is from a previous single finding before shaft was filled and some galleries restored.
A nice cobaltoan calcite specimen showing concretionary growths with a good and deep colour. The mineralization is filling fissures of the Triassic conglomerates, which are very 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 huge size cobaltoan calcite specimen showing concretionary growths with a good and deep purple color. The mineralization is filling fissures of the Triassic conglomerates, which are very visible in this specimen and with a cavity that gives an aesthetic shape.
One side shows a polished section where we can enjoy perfectly banded purple calcite and conglomerate individual clasts. On the other side fracture is totally natural and not polished. 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.

A very rich and huge size group of sharp metatorbernite crystals showing tetragonal forms, an intense green color and good luster. They show a classic polysynthetic and echeloned growth and some vugs from its stalactitic origin on the back side. 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.

Rich group of small hexagonal prismatic pyromorphite crystals with an intense green color partially covering a vug on a limonite rocky matrix. Crystals are very sharp and color very uniform. From a Spanish locality not well represented in collections.
On a matrix totally covered by sharp quartz crystals, some of them with small inverse scepters, one of them more developed shows a perfect scepter shape. An elongated hyaline quartz prism with a scepter on the top with a pale amethystine tone. Really nice miniature.
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.
