Aesthetic group of sharp anglesite crystals, very brilliant, transparent and richly faceted. They are disposed on a matrix of galena. An old specimen from the Manchion Collection, very luminous, from this classic Moroccan town.
Group of sharp gypsum crystals, transparent, lanceolated, with defined faces and edges. A classic from Spanish mineralogy.
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... With the label from Manchion Collection.
Aesthetic group of several descloizite crystals. Every one of these group of crystals is a group of little crystals of slightly curved edges, a typical shape in the classic samples from Namibia. Intense brilliance a deep color. From this former Sapnish collection.
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.
This specimen shows an arborescent growth with deformed crystalline forms and other idiomorphic in some areas of the specimen, with well defined faces and edges. With good color and brightness which is not very frequent. With small quartz crystals.
Specimen of native copper with arborescent and dendritic growths formed by rounded crystals, partially covered with cuprite. Good size. From this classic Moroccan mine.
Rich group of hexagonal prismatic pyromorphite crystals. Some of them with hoppered forms and marked color zoning. Excellent green color, brilliance and with translucent crystals. A specimen of good size and exceptional quality. Today it is difficult to find them in the market, if we take note that they were seen more often years ago.
In this specimen we can enjoy several groups of wire silver, with showy wire to skeletal growths and metallic luster. Accompanied by black acanthite crystal aggregates. From a classic locality for the Catalan and Spanish mineralogy. A good chance to represent this locality in your collection. Nowadays it is very difficult find specimens, only from old collections...
In this specimen we can observe very aerial growths of skeletal native silver, accompanied by acanthite. Intense luster. These specimens come from the findings of the last years of the XXth century, being today very difficult to find them in the market and less with this quality.
In this aesthetic specimen we can enjoy numerous groups of silver filiform crystals with skeletal growths, brilliant and of a bronze tone. They are accompanied by some acanthite crystals. These pieces come from a classic locality of the Catalan mineralogy such as the Balcoll mine. On a matrix with calcite. Almost impossible to get today and less with this quality.

In this specimen we can observe numerous skeletal growths of native silver, accompanied by octahedral crystals (with some cube faces) of acanthite and, very interesting, several cube octahedral galena crystals. These specimens come from the findings of the last years of the XXth century, being today very difficult to find them in the market and less with this quality.
Acanthite in the specimens of the Balcoll mine, usually appears in small crystals. In this piece there are several groups of acanthite crystals of good size, showing facets of the cube and the octahedron, some of them have grown on skeletal aggregates of native silver. Very interesting for the species and for this classic Catalan locality. These specimens come from the findings of the last years of XXth century, being today very difficult to find them in the market and less with this quality.
Glaucophane is an unusual species member of the amphibol group. This Italian locality is known worldwide for the good specimens of this species. It is usually covered with calcite, which once removed shows sculptural aggregates of striated tabular to prismatic translucent crystals, with an intense bluish-gray color, almost violet. In the cavities appear small orange crystals of rutile and groups of chromian muscovite (var. fuchsite). Pyrite crystals also can be found. A good sized and very aesthetic combination from this classic locality.
This English specimen shows us a group of calcite crystals, one of them of larger size, interpenetrated, twinned, with a color between honey to white. With defined faces and edges, translucent. In the back it shows a exfoliated part. A sample from a mine not well represented in collections. From the Adrian collection, a dealer and collector from the United Kingdom. Label will be send with specimen.
These specimens of wulfenite with the chocolate brown to orange tone are very appreciated by collectors and very difficult to see today, unless they come from former collections with tradition. This specimen shows a large group of tabular crystals, very brilliant and translucent, few small nick that does not affect the aesthetics of the specimen. A classic piece.
Very curious specimen of hydroxylapophyllite-(K) formed by numerous crystals inside a geode resembling a nodule. They are accompanied by small needles of calcite very fluorescent (bluish).
Very rich curite specimen, with some intense orange color crystals and the rest black due to being coated by heterogenite. The sample comes from the former Coune collection and according to its owner was adquired from the 90s, but specimen could be older. Curite crystals are disposed in a very contrasted way on the white matrix. From the type locality for the species.
Two crystals of elbaite in parallel growth. Intense color, with greenish transparence on the upper part. Striated prismatic faces with very clear terminal rhombohedrons. A little gem...
Curious specimen of a classic locality formed by numerous galena cube octahedrons. They have very defined forms, idiomorphic crystals but hollow inside. They upholster the dolomite matrix. for lovers of the curiosities from Moroccan mines. An old sample.
The label of this specimen reads "Sevilla". In the catalog of the Manchion collection it is mentioned that this piece of schorl-dravite was acquired to Dr. Joan Viñals, at the Granollers fair in 1988. For that reason, in the absence of more info, we will leave this wonderful Andalusian region as its origin. M. Calvo talks about tourmalines in pegmatites from the Los Ángeles mine, near El Castillo de las Guardas, in Seville.
Group of very well defined cuprite crystals showing very unusual facets both for the species and for this classic locality for the species. They have very well defined faces of the cube and the octahedron, together with those of the dodecahedron. Under intense light the red transparency is observed, but the surface shows a gray patina, the years have passed away. They are placed on a cavity of brilliant calcite crystals. An interesting rarity.
