Very rich group of cinnabar crystals, well defined, rich in faces, with a really intense red color that grows when the light crosses them. They are accompanied by several crystals of dolomite. Very aesthetic specimen.

Size: 8.0 x 4.6 x 2.5 cm.
Main crystal: 11 x 11 mm.

These specimens were collected in an outcrop situated between the villages of Malpartida de Corneja and Casillas de Chicapierna, in Ávila. They are floating crystals of twinnen orthoclase (Karlsbad) those have been partially or totally pseudomorphized by quartz. They present visible forms of the twin, with altered faces with curious cavities. Some specimens still preserve an orthoclase crystal core. This pseudomorphosis is very unusual.

A very rich specimen of Ardennite-(As), a rare silicate arsenate of manganese and aluminum, which has the type locality in this Belgian town. Formed by some  aggregates in parallel growth of prismatic flattened crystals, intense color between orange to yellow and luster. They are included in a quartz matrix with hematite. Collect samples is currently prohibited and specimens are very difficult to find (I know it). From the collection of P. Van Hee.

Anapaite nodules of the Bellver de la Cerdanya area are a classic of the Catalan and European mineralogy. The materials where these nodules appear are part of the filling of a deep lake of the upper Miocene that developed in the southern part of the Cerdanya basin.
This specimen presents a good size nodule, with an internal part with a septaria structure, completely covered by small but very brilliant and transparent green crystals of this rare iron and calcium phosphate. We will send both parts and if you want you can preserve them closed... :)

Scolecite and aerinite specimens from this small Aragonese town are known worldwide. This specimen shows groups of acicular prismatic crystals those form globular aggregates which, when extracted, they allow us to see the radiated growths perfectly. Snowy white color and good luster. Samples of this quality and size are rare and less nowadays.

Hisingerite is a rare hydrated iron hydroxylsilicate and its type locality is Riddarhyttan (Sweden), near from this specimen locality we offer. This sample shows radial laminar aggregates with an intense dark brown to almost black color, with metallic luster. Specimens of hisingerite are very rare and this piece is from the collection of Renaud Vochten (1933-2012), a well-known Belgian collector of mineralogical rarities. This specimen was adquired by Mr. Vochten in 1975 to V. H. Sørensen.

Size: 7.2 x 6.5 x 3.8 cm.
Found in ca. 1975.

Very rich group of wulfenite crystals, prismatic to tabular, intense orange color with color zoning. This specimen comes from the type locality for the species: Bleiberg, and it is accompanied by an old label: A. Bohländer, pharmacist. In the label we can read "gelbblei" or yellow lead, old name for this species. A historical specimen, from the type locality, with good size and quality... There is a very interesting article about this classic mining locality in mindat: "Collecting Minerals at Bad Bleiberg" by Rudolf Hasler.
