Rich group of pyrrhotite crystals forming rosettes of tabular crystals of hexagonal shape, with an exceptional brightness. They are disposed very aerial on a matrix partially covered by quartz crystals and dolomite. An exceptionally aesthetic sample from these classic mines.

Groups of orange rosettes of this rare species. Tinzenite is a boro/aluminosilicate of calcium and manganese from the axinite group [see here], and probably the best specimens are from this Italian mine. Also accompanied by quartz crystals and white to pink kutnohorite aggregates.

Vug in basaltic matrix lined with extremely fine acicular crystals of mesolite. From a German locality not well represented in collections.

First appointment for this Moroccan locality. This lead, iron and rich copper sulfate has been analyzed by SEM-EDS, we will send results to the buyer. Beaverite-(Cu) forms yellow earthy masses formed by lenticular crystals. It is accompanied by fibrous malachite crystals and azurite crystal aggregates. In the matrix we have observed the presence of cerussite. Only the combination of colors and species in  this sample is aesthetic itself.

Group of very sharp and tabular wulfenite crystals, with an excellent brilliance, red color and from translucent to transparent. They are disposed as rossettes on a matrix of goethite. Main crystallographic forms we can be observe are the first and second order tetragonal pyramids, truncated by the pinacoidal faces.

These specimens often have some crystals with small breaks, in this sample there is only a small fractured crystal, not visible. It is one of the most complete and damage free specimen I found.

From a recent find in the area of La Celia mines. This crystal is very rich in faces, doubly terminated, gem quality, very brilliant and with an excellent transparence. It is accompanied by numerous other smaller crystals. A very interesting specimen.

Very aesthetic quartz (eisenkiesel or Jacinto de Compostela var.) crystal, showing defined faces and edges, with a good size for the locality. Perfect luster, with deep red color. In a gypsum matrix with another small crystal. From a different Spanish locality than usual ones.

Excellent specimen of fluorapatite from "Jumilla".A group of crystals, one of them predominant, vertical, isolated, brilliant, transparent, with good color and no damage. It is disposed in a cavity accompanied by globular aggregates of calcite and laminar hematite crystals. This specimen is from dumps and already have a certain age. Interesting matrix: A very esthetic and representative piece from this classic Spanish locality were nowadays is forbiden collect minerals.
This locality is located in La Celia volcano where we find remains of a volcanic neck (chimney) and streams from Pliocenic age (1.8 - 5 million years). These mines have a special geological interest, as they contains an exceptional locality for fluorapatite in the volcanic rock "jumillite". Jumillite is a volcanic rock of the lamproite group, a variety of phonolitic leucitite, consisting essentially of diopside and leucite and, to a lesser content, by olivine, alkali feldspar and phlogopite.

A very rich group of fluorite crystals, with an excellent transparence, brilliance and with a slight pink to violet color, near colorless. With defined cubic faces and dodecahedron on edges. Excellent miniature.

This specimen is a defined crystal of fluorite, with geometric violet color zoning, good transparency, brilliance and cube and dodecahedron faces. Presenta some small damage in the back. Good miniature.

A very rich group of goethitized pyrite crystals, covered by a thin layer of limonite, from this classic Spanish locality. Defined crystals and orange color. Good size specimen.

Excellent specimen of galena that shows a group of sharp cubic crystals, brilliant, interpenetrated and which are peppered by small crystals of honey color sphalerite. Partially covered by sharp, brilliant quartz crystals and minor calcite. This deposit has been operated by several french compagnies from 1923 to 1960. A quality specimen for this Moroccan locality.

Galena crystal on fluorite from Fontsante. The cube crystal is truncated by octahedron faces. It shows a bluish color due to the natural iridescence. Perfectly disposed on a fluorite matrix covered by brilliant small quartz crystals. It was collected in the Saint-Augustin vein (known for its sulphides). It is no easy to find samples with this quality from this French locality. This former fluorite mine started works in 1919 and closed in 1987.

Group of interpenetrated aragonite crystals, brilliant, damage free and with a more intense brown color zoning in central prism. With naturally corroded pinacoids. A good specimen different from the usual in this classic aragonite Spanish locality.From a former collection Botella.

Curious globular aggregates formed by numerous fluorite octahedral crystals that have grown together, reaching this globular shape. If you look closely under magnification the specimen you can observe different growing phases. Very fluorescent under LW-UV.
This green color is the best ever found for this site, with transparence and brilliance. They are disposed on an matrix of hard porphyry covered by minute quartz crystals, with calcite and goethitized cubic pyrite.

This area is known as Singuerlín (a neighborhood of Santa Coloma de Gramenet city, close to Barcelona) and from 60's collectors has found these globular aggregates with tones between white, yellow or slightly greenish. Then some specimens were analyzed and labeled as gearksutite. More recent analysis did not indicate the presence of this species but only fluorite.

Good size specimen that shows a rich group of stalactitic growth of chalcedony, a variety of quartz. They are disposed randomly on the goethite matrix. Colourless, yellow and orange tones, due to the iron oxides. A very aesthetic specimen from this classic quarry.

An aesthetic globular aggregate of prehnite, disposed very aerially on a matrix covered by several needles of actinolite. Translucent, with a green color with yellowish tones. From a classic Spanish locality.

This aesthetic specimen shows a very rich group of acicular cyanotrichite aggregates, with a deep blue color and brilliance. They're accompanied by green globular aggregates of parnauite. Also we can enjoy groups of green-blue hexagonal chalcophyllite crystals, perfectly defined. The matrix is covered with different iron arsenates. A piece of a classic French mine where today is impossible to get specimens, and less of this quality.

Botryoidal aggregates formed by goethite microcrystals, with a delicate velvety appearance with deep brown to black color zoning. In section we can observe the radial arrangement of goethite crystals. The matrix is a mixture of goethite with some siderite rhombohedrons. These specimens are from a find in the Mont-Roc mine, that is known for the French mineralogy for its brilliant goethites and fluorite.
