A very nice specimen of this classic Basque mine. It shows a dolomitic matrix partially covered by brilliant sphalerite crystals, defined faces and slightly curved edges. Excellent transparence and toasted honey color. It is accompanied by some greenish siderite rhombohedral crystals and dolomite crystals. A complete and brilliant specimen from this mine. From the Manchion Collection.Troya Mine was closed in 1993, only a few years before these specimens were collected in 1990. Nowadays the mine is collapsed and flooded. This specimen was in a former German mineral collection since then. 13295q

Group of fluorite crystals, cubic shape, brilliance, transparence and violet colour with geometric zoning. Some of them presents minor nicks, without affecting the whole. They are accompanied by barite crystals partially covered by tiny, shiny quartz crystals.

Druse of small quartz crystals, some doubly terminated, partially covered by white kaolinite. Peppered by several anatase crystals, with dipyramidal faces, truncated by basal pinacoid. Very sharp, translucent and with a toasted honey tone. Very aesthetic and rare in the market.
It is interesting to say that recent analysis of the reddish ashlars of the Torre Nueva (New Tower) of the Astorga cathedral indicated that these building materials were extracted from this Cantera del Moro during XVIIth and XVIIIth centuries.

Group of sharp calcite crystals, with rhombohedral flattened shape, translucent. From a unusual locality not well represented in collections.

Sold

Good sized rounded, globular crystals of lilac-pink lepidolite. This formation is also known as ball-peen lepidolite after the resemblance to the round end of a ball-peen hammer. Lepidolite is a Li-rich member of the series between polylithionite and trilithionite. A very aesthetic specimen from Manchion Collection.

Good schorl specimen from the clssic locality of Cap de Creus, Girona. Some crystals showing a developed and faceted prism and terminal faces, some of them with good thickness. From this locality it is very difficult to obtain specimens if they do not appear in old collections, as it is the case, since it is totally forbidden to collect specimens in the area. This one belongs from the Manchion Collection and it is accompanied by the handwritten label.

These mines are located in the heart of Massís del Montnegre, in Catalunya, and it is a classic for mineral collectors. The "vesuvianas" are found mainly in the outer zone of the mines. In this old specimen we can enjoy a radial aggregate of vesuvianite crystals, of good size and with the beige-greenish color that characterizes them in this locality. In a small vug we can see greenish transparent and well formed crystals of the species.

Aggregate of sphalerite crystals, with complex faces and intense color when the light es through it. Back side is exfoliated. From this classic locality.

Fragment of a sphalerite crystal, with complex faces and intense color when the light es through it. Back side is exfoliated. From this classic locality.

From this locality you could find samples in the market, but with a group of interpenetrated crystals, rather few. A curiosity...

Radiated aggregates of Tremolite from this classic Catalan locality. Specimens were found in a Cambrian-Ordovician marbles with calc-silicate levels. Outcrops at an altitude of 2700-2800 m, near Pic de l'Infern (Hell's Peak), 2870 m.

Sold

Specimen formed by cyclic twins of bournonite, with gray metallic luster. Theyu have rounded faces and edges, good luster and is disposeded on a matrix of defined crystals of sphalerite toasted honey to black tones. A classic from this French mine.

A nice azurite miniature, with good brightness, intense color and sprinkled with malachite rosettes. An aesthetic old piece from this classic Moroccan locality.

In this old specimen from Manchion collection we can observe several octahedral gahnite crystals with defined faces and edges, a uniform deep blue color and accompanied by yellowish sphalerite. Such samples are very difficult to obtain and only from time to time appears a classic like this, only from old collections.

Sold

Rich aggregate of diopside crystals, with an intense apple green color. In the cavities we can observe the shapes of the lanceolate prisms. From a classic Catalan mine, from which it is difficult to obtain samples. A local curiosity.

A classic old-time specimen of hydroxylherderite, well crystallized, with sharp translucent idiomorphic monoclinic crystals. Lustrous and with a greenish-yellow tone. Associated with albite and muscovite from the Golconda pegmatite in Brazil. From Manchion Col., purchased in 1987 to Dr. Joan Viñals. Previously misidentified as herderite. Previamente mal identificada como herderita.

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 cium sulphide is a product of the alteration of rich Cd sphalerite. It is impossible to get specimens today.

Aesthetic sample formed by sharp cerussite crystals, translucent, twinned, with a very good luster, slightly honey tone. They are disposed on a matrix with galena. From the Manchión collection.

Sold

Rich group of danburite crystals, transparent to translucent, with developed prism and defined faces and edges. Some with nicks in the terminal parts, but without affecting the whole. They are disposed on a matrix with pyrite and sphalerite crystals. Brightness, snowy white, very aesthetic and ancient specimen.

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.
