Small but interesting specimen of curite that presents groups of brilliant acicular prismatic crystals with an intense orange color. Observed under the microscope we can see that they have transparency and are accompanied by yellow crystals soddyita. This radioactive mineral is named after Pierre Curie (see wikipedia) and this sample is from Shinkolobwe, the type locality for the species. A chance to get a piece with curite crystals.

A rich druse of cuprian adamite crystals which is completely covering the cavity in limonite. With stalactitic growths showing an intense blue-green color. They are peppered by small white globular aggregates of smithsonite, along with areas of rosasite green. Accompanied by globular aggregates of conichalcite and very defined cuprian adamite crystals. An interesting specimen with good size.

Group of interpenetrated cubic fluorite crystals with violet tones and delicate color zoning, transparence in some crystals, most being translucent. Characteristic for fluorite of this mine are the corroded faces. They are disposed on a matrix of iron oxides. What I also would like to emphisize of this piece is the mine from which it comes, near Alumbres in Cartagena, not well represented in collections.

Group of interpenetrated pyritohedrons on matrix from a classic Spanish locality as Ambasaguas. Very sharp faces and edges, intense golden color and excellent luster. The perfection of the Rioja pyrites.

Interesting and old specimen of annabergite showing bright green flattened prismatic crystals with transparence. They are disposed in cavities of the dolomitic matrix. From Laurion, an European classic locality. The specimen is accompanied by an old label from XIX century from an unknown German collection (till today).

Sold

Group of sharp fluorite crystals showing cubic forms distinguished by their delicate green apple color. Good transparency and good brilliance. They are partially covered by brilliant clusters of hyaline quartz. A bright piece from Morocco.

A novelty in the Castelló mineral show 2014. This is a group of aragonite crystals showing very aesthetic flos ferry structures, with good brilliance and white color, slightly brownish tones at the terminal crystals. It comes from a Almerian mountains well known for its hot springs.

Excellent combo formed by a group of ferberite crystals with parallel growths, with an intense black color and good brightness, peppered by lenticular siderite crystals. They are supported by a hyaline quartz crystal partially covered by muscovite. Note that quartz has a small dent on one of the faces of the terminal rhombohedra, without affecting the aesthetics of the sample. Arsenopyrite has grown on the ferberite. A specimen with a superb aesthetics, from a classic locality like Panasqueira.

This specimen is very rich in lanceolate clinozoisite greenish crystals, bright and sharp. They are accompanied by groups of quartz with well-developed prism according to the main axis. A Peruvian locality not well represented in collections.

These crystals show astonishing sharpness of tetrahexahedron faces, together with the less developed cube. Crystals are uncolored (under halogen light) or slightly bluish (under fluorescent light), bright and completely clear and are scattered over an esthetic matrix of white crystals of barite. A high-quality specimen that belonged to the Silvane (Barcelona) collection.

Sold

Bipyramidal crystal of powellite with a good size, very brilliant and well defined faces and edges. With a delicate honey color and some transparence. It is accompanied by stilbite crystals on matrix.

This specimen is showing a very rich group of allanite-(Ce) crystals, disposed randomly on a cavity covered by dolomite and calcite. This mineral with Rare Earth Elements (REE) is a classic for this French quarry, in the Pyrenees. It shows very elongated prismatic crystals, with transparence and brown to toasted honey tones.

From a recent find in the Valentín open pit, we get these hemimorphite specimens showing aggregates of flattened prismatic crystals as aesthetic rosettes. They are partiallly filling cavities in the matrix. These samples have been analyzed and we will send a copy to the buyer.

Group of fluorite crystals with faces and sharp edges. One of them shows a good size for the locality. Its intensely toasted honey color is very particular. Note that it is extremely fluorescent with a yellowish tone. It is accompanied by several tabular crystals of white celestite and a group of calcite. It is difficult to find in the market samples of this mine without damages (this only has a almost invisible small dent) since they "fall down" in the geodes. An aesthtic American classic.

Group of fluorite crystals with echeloned parallel growth, with marked faces and edges and damage free. Its honey color is very particular to this locality. Note that it is extremely fluorescent with a yellowish tone. Accompanied by white celestite crystals and disposed on a matrix with dolomite and calcite. It is difficult to find in the market pieces from this mine without damages, because they use to "fall down" in the vugs. An aesthetic American classic.

A piece with history. This is a specimen of elongated prismatic barite crystals with toasted honey tones and very good transparence. It shows very sharp prismatic and terminal faces. These specimens are uncommon in the market. It comes from the former Daunis (Barcelona) collection. Very representative.

Sulfur crystals from the marble quarries of Carrara are appreciated worldwide for its gem quality. In this specimen, we offer a sulphur crystal perfectly disposed on the marble matrix. This crystal is very rich in complex well-defined rhombic faces. It is uncommon because they appears usually rounded. The brilliance and transparence are incredible. The color is intensely yellow, very characteristic of these Carrara sulfur specimens. An exceptional and definitive displaying sample, very rare on market, considering that in last years it has been found only few specimens of this size and quality. A great opportunity.

A very rich group of pyrite crystals forming a globular aggregate, very brilliant, with an intense color and hinting cubic faces. It is disposed very aerial on the matrix with rhombohedral calcite crystals and yellow fluorite. To increase its aesthetics a single calcite crystal has grown on the pyrite. A unusual specimen for this mine where pyrite is often found in small crystals coating the fluorite.
