Curious specimen of greenockite of this classic locality of the Catalan mineralogy. Under loupe, aggregates of intense yellow color are observed, with reflections of what could be crystalline faces. This cadmium sulphide is a product of the alteration of rich Cd sphalerite. It is impossible to get specimens today.

Very, very aesthetic specimen, unusual, showing two globular aggregates of smithsonite, colorless, transparent that let us see a whitish crystal aggregate core, with very curious growth. They are accompanied by small crystals of the same species in the form of globular grains. To give a touch of color and quality, several aggregates of olive green adamite crystals, visible terminal faces, bright, translucent and sprinkling the goethite matrix. It is an exceptional and rare old material from the Manchion Collection. Probably this specimen comes from the Palomas Oriente area of the mine. Pure aesthetics...

Floater specimen. Excelent group of vanadinite crystals showing a defined hexagonal shape, with very well defined faces and edges, intense red color. Good brilliance and some transparence, with internal reflections between red and orange. Crystals size is remarkable. A piece with two faces. One of them, crystals are disposed in an isolated way on a barite lenticular rosette crystals. In the other, they are forming rich crystalline groups. The presence of this baryte matrix is highly appreciated by collectors and gives to the specimen a special aesthetics.

We have labeled this specimen as fluorite, because it highlights a group of crystals of this species, transparent to translucent, with complex facets of the dodecahedron, with faces with polysynthetic growths. They are disposed in a vug of bright rhodo crystals and intense pink. A second generation of rhodo forms globules of honey tone. A very curious and aesthetic Mina Uchucchacuapiece.

These specimens were found in a outcrop close to Maria Magdalena mine, close to the beautiful town of Ulldemolins (Tarragona, Catalonia). Probably, these crystals are the most defined crystals of Čechite worldwide. They are brilliant, black color and show a tabular shape defined by different order orthorhombic prisms and pinacoidal faces. Disposed very aerial on a fluorite matrix.
Čechite is very rare lead iron vanadate that is only found in a few places in the world and it is the first citation in the Iberian peninsula.
SEM-EDS and EPMA analysis show that, in some cases, on the crystal surface there is Cu²⁺ has been formed but the crystal is pure PbFe²⁺(VO₄)(OH). In most specimens (all) from other localities the presence of manganese is important, but these specimens are Mn free. We will send more details to the buyer.

Nowadays, graphite specimens from this classic Asturian locality are very difficult to be found. These specimens show contiguous columns, with greasy luster and defined hexagonal forms. The crystal habit of natural graphite in most cases is determined by its highly anisotropic, layered structure. However, anomalous habits of graphite,determined not only by its structure, but also by the peculiarities of the growth environment, are frequently encountered, and optimization of the space available when solidifying forming columns.
