Rich group of very elongated mimetite crystals, some of them doubly terminated, brilliant, translucent and with a soft yellow tone. Mimetite specimens with this shape are unusual in Ojuela mine, usually globular. They are accompanied by aggregates of tiny yellow to orange crystals of tsumcorite-arsenbrackebuschite. They are disposed in a cavity of the goethite matrix. The specimen has been analyzed and the results will be sent to the buyer. It has been published in the mineral magazine "Paragénesis" (1-2017).

A very sharp anatase crystal showing the tetragonal dipyramid, truncated by the pinacoidal faces. Brilliant, with almost black color but with bluish reflections, metallic luster. The crystal has a small damage in the back edge, which does not affect aesthetics. With a minor quartz crystals matrix. These crystals appear in the Alpine fissures, most of which are found in the Hardangervidda National Park. A classic European piece from many years ago.

From a Bulgarian mine rarely represented in collections we offer this interesting specimen of pyrite with very unusual cubic forms. The crystals have a tabular shape with terminal faces of the octahedron. They are very aerially disposed on a matrix with quartz crystals. A crystallographic and locality rarity.

A good sized almandine crystal from this not well known Galician locality. Crystals usually appear included in a green schistose matrix. They show defined dodecahedron faces and rounded edges. With a deep red color. From a recent find.

A very rich specimen formed by several aggregates of acicular to prismatic pyromorphite crystals with an intense green color and silky luster. On a rocky matrix. A French classic from old "times".

On a matrix of stalactitic goethite, with a deep brown color, numerous prismatic crystals of pyromorphite are disposed, many of them doubly terminated, between translucent to transparent and with a delicate green color. The specimens of this Italian mine are very unusual in the market. Very interesting and aesthetic speciumen.

The baryte specimens of this Italian mine, which finished its work in the 80's, are considered among the best European classics for the species. This specimen presents a rich group of tabular crystals, with sharp edges and faces, excellent transparence and a superb toasted honey color. It emphasizes among them a crystal of more than 5 cm. Nowadays it is very difficult to find these samples with this quality. An European classic.

Group of calcite crystals disposed isolated on a matrix of brilliant quartz crystals. These calcite crystals show forms of the prism and rhombohedron in the terminal faces, with a slightly darker core related to the scalenohedron. It is an old specimen from a classic locality for Catalan mineralogy.

Very aesthetic group formed by sharp cubic crystals of fluorite, some of them interpenetrated, very transparent and with an excellent brilliance. They show a very uniform apple green color. They are disposed in an matrix of quartz crystals

Rich group of lanceolate baryte crystals, with well defined faces and edges, brilliant and transparent. We can see a certain color zoning. The exact location of these specimens is not known since, according to the information available, they appeared in 2007 as coming from Xichang, sure from the mining works in the area. A brilliant and aesthetic specimen.

Pyrite cluster formed by some interpenetrated crystals, with marked striated cube faces and pyritohedron. Faces and edges have a characteristic curvature. Excellent brilliance. These are specimens with more than two decades from this classic pyrite Spanish mine.

This good sized pyrite specimen shows us several interpenetrated crystals, two of them dominant, with marked striated cube faces and pyritohedron. Faces and edges have a characteristic curvature. Excellent brilliance. Only two small corners are dinged. These are specimens with more than two decades from this classic pyrite Spanish mine.

Rich group of fluorite crystals, cubic, transparent and very brilliant. With a yellow color with greenish tones. They are partially covered by snowy white rhombohedral curved dolomite crystals. From a classic Spanish mine.

A floater nodule with blackish and whitish spheroidal forms with some visible crystalline faces. They're a silicified fossil sponge which have preserved the original morphology of the biological specimens.

Rich group of cubic fluorite crystals, very sharp, transparent and with a greenish to yellow tone very characteristic of these fluorites. This specimen is from the mines of Sant Marçal (also called of the Matagalls Mt.), located in the massif of El Montseny. Nowadays not many samples are seen with this quality. A classic of the Catalan Mineralogy.

These hematite specimens belong from ancient finds (ca 1980s) in a mine located on the property of the Piquín farmhouse. In this huge size sample we can see an aesthetic botryoidal aggregates, with an exceptional luster. Even botryoidal "negative" cavities are observed, inward. In the fracture zones of the specimen, radial fibrous aggregates forming botrioids are revealed. A piece of quality without equal and very difficult to find nowadays.

Pyroaurite-2H is a polytype formerly known as sjögrenite (discredited). This specimen belongs from a classic Italian locality for the species. A matrix of marble with calcite on which stand out numerous foliaceous aggregates of tabular orange color pyroaurite. This specimen has its pedigree in the collections Pierini and Vochten. The label of the latter accompanies this interesting piece.

Senegalite is a rare aluminium phosphate. In this specimen we can observe several prismàtic transparent crystals on blue turquoise. This specimen is from the type locality for the species.

Superb and brilliant specimen formed by botryoidal aggregates of malachite, of intense green color, and covered by small hyaline quartz crystals. Quartz gives it this aesthetic brilliance. Matrix is formed by a stockwork of altered chalcopyrite. Malachite specimens from this locality and with this shape are unusual.

Druse of trapezohedral crystals of andradite from this classic Spanish locality. Intense brilliance, with colors between brown to reddish. On a granatite with epidote. This is a specimen with pedigree from the Gustav Beck collection.
