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.

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.

The matrix of this sample is defined by a druse of quartz crystals, between milky and hyaline, very well defined, short prism and brilliance. These crystals are peppered by various pyrite aggregates. What stands out, very aerial, is a group of barite tabular crystals, very bright, also dotted with small pyrite-marcasite crystals. An exceptional piece for display, excellent for this mine.

Historically the most representative fluorite specimens from mina Moscona are yellow, recently some of violet tones have been collected. This ancient specimen is one of the few that appeared in the mine with this pink to purple color, with zoning.

They are partially covered with sharp tabular barite crystals, between transparent to opaque on the outer edges. No damage, good size and fluorescent (UV-LW). A very unusual piece for this classic Spanish mine, from a former German collection.
