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.

A floating specimen, all brilliance. It is a rich group of crystals with dominant cube and dodecahedron faces. One of them stands out for its size and the large number of cube, dodecahedron, octahedron, pyritohedron faces. As we said, nice luster and characteristic golden color. It presents small damage without affecting the quality of the sample. An excellent specimen from this Peruvian mine.

Group of barite crystals with parallel growth, between transparent and translucent, with brilliant, honey to yellowish tone and with defined tabular shape. An aesthetic specimen with a minor marcasite matrix.

A huge size rhodochrosite crystal with an intense red color and well defined scalenohedral forms. Good color and transparence. On a solid rocky matrix with hyaline quartz and cubic fluorite crystals (fluorescent). A good specimen hard to find...

Two generations of vanadinite crystals. A good-sized brilliant crystals, with echeloned growths and defined faces and edges. With good color yellow and peppered by deep black coronadite globular aggregates and covering the matrix. Another generation shows small crystals (<1 mm) but with a nice luster, transparence, and yellowish tone. Both are on goethite with mottramite crystals.

A very curious piece composed by a group of quartz crystals, one of them of greater size, with a slight smoky tone and an exceptional transparence. Black almost metallic inclusions of hematite are observed in the top faces of the crystal. Also on them. With a minor feldspar matrix. A very aesthetic specimen.

Large group of sphalerite crystals with an exceptional brilliance, honey color and transparency that allows light to play with the honey colors. Peppered on back side by small crystals of baryte showing flattened shapes. A little gemmy miniature. Troya mine was closed in 1993, only a few years before these specimens were collected in 1990. Nowadays the mine is collapsed and flooded.

Aesthetic crystals of bournonite, twinned, with echeloned growths, very bright and sharp. They are disposed on a matrix with lenticular siderite crystals. It is hard to find samples of this classic German locality. If on hand they are all brilliance, under loupe crystals are amazing.

Rich group of cubic crystals of fluorite, of intense color between violet and purple. They are disposed on a matrix of baryte, with tabular crystals in book shape, dull luster and zoned. Good size for display...

On a white matrix formed by several white dolomite crystals, sharp and with curved faces and edges, we can enjoy a crystal of sphalerite very brilliant, with transparence and a very uniform toasted honey color. Very aesthetic specimen. From a former German Col. Nr.812.
