Globular growths of barrel-shaped orange yellow to green crystals with a good luster. The crystals are on a matrix with small crystals of quartz.

Group of rhombohedral smithsonite crystals, with a pink color. Accompanied by a group of quartz crystals. From a classic worldwide locality for mineral collectors.

A very rich group of mimetite globular aggregates, with yellow tone and brilliant. Acompanied by hemimorphite lanceolated crystals of hemimorphite, transparence and brilliance.

Pure crystallography... Very nice galena crystal showing cube and developed octahedron faces. Perfectly disposed on a grenalitic rocky matrix with siderite.

A very sharp and brilliant fluorapophyllite-(K) doubly terminated crystal with good size and showing the forms of the tetragonal prism, dipyramid and pinacoid. Note the greenish to reddish inclusions, probably chlorite and iron oxides, that we can see in the back side. A very interesting specimen.

Group of huge sized fluorapophyllite-(K) crystals, one of them dominant and doubly terminated. They present forms of the prism and dipyramid tetragonal. Brilliant and defined. Particular greenish to reddish inclusions, probably by chlorite and iron oxides. A very interesting specimen.

In this floater specimen we can observe a group of quartz crystals, two of them clearly dominant, with well defined faces and edges. We see a well-developed prism with rhombohedral terminal and trapezohedron faces. Transparence and brilliance are both excellent and with a very uniform smoky tone.

An exceptional specimen. It shows a well-formed cyclic twin of cerussite crystals, well defined, bright, colorless and transparent. They are disposed very aerial on a matrix with malachite and some other crystals of the same species, also twinned but in "V" shape. A full aesthetic specimen of this very appreciated mine.

A group of cerussite crystals from this classic mine. It is a very interesting specimen because one of the crystals shows a very unusual number of faces. It is transparent, brilliant and with tabular shape. Color is slightly yellowish and with inclusions. With some ciclic twins. Good one. From the collector and dealer Luis "Louie" Antonio Bravi Teixeira Leite (1942-1999).

Very rich group of smithsonite rhombohedral crystals. Light pink color, brilliant, transparent. A very interesting piece of this famous mine.

Very rich group of smithsonite rhombohedral crystals. Pink to reddish color, brilliant, transparent. A very interesting piece of this famous mine.

In this specimen we can see a group of lenticular sturmanite crystals, brilliant, with well defined faces and edges. Color is yellow to greenish. Noted for its size and transparency. A very good choice...

In this specimen we can enjoy a rich group of lenticular sturmanite crystals orange, bright, with a yellow to orange color, transparent and with very sharp faces and edges. It is accompanied by rosettes of greenish brucite, a magnesium hydroxide. In the same specimen there are two very interesting species for systematic and aesthetic collectors.

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 white epimorphic crystals (after not determined species) of a rare Mn oxalate: lindbergite.

A very aesthetic specimen formed by several fluorite cubes with echelened and polysynthetic growths. Nice color and luminous. A different specimen from Berbes.

Most people do not know that these come from anywhere but Utah, but here is a Kalahari Manganese fields bixbyite specimen. A druse of highly lustrous, very sharp interpenetrated cubes of black bixbyite from this famous locality. An excellent specimen for the locality. A true rarity.

Very good specimen of bultfonteinite forming white acicular crystals, with prisms slightly beige to orange of olmiite. Two rare species from a mining area well known for systematic collectors. Accompanied by tabular celestine crystals. Good size and better quality.

Group of fluorite crystals, transparent, bright, with very sharp faces and edges and showing forms of the cube. One of the crystals has a very interesting asymmetrical face. Grayish-blue color, depending on the incident light. On an matrix covered by hyaline quartz crystals.

A rich group of well-defined cubic crystals of fluorite showing polysynthetic growth on faces. Violet-purple color is very intense. Many of them are interpenetrating, giving the whole a unique aesthetics. From a classic Asturian locality.

Exceptional group of cubic fluorite crystals with sharp faces and edges, matt brilliance and good size. It highlighted by the deep violet color, with marked geometric color zoning. An old piece from a classic locality for Spanish fluorite .

This specimen is formed by a group of fluorite crystals, interpenetrating, showing echeloned growths on their faces. Very brilliant and with violet color zoning, more intense in the crystal core. They are disposed on a small matrix with quartz crystals.

This excellent specimen of galena comes from a classic ancient German lead-zinc mine. It shows a group of cubic crystals, interpenetrated. Good metallic color and luster, perfectly disposed on a matrix of dolomite crystals peppered by tiny chalcopyrite. It is a perfect miniature collected in the 60s, a German classic.

This excellent specimen of galena comes from a classic ancient German lead-zinc mine. It shows a group of cubic crystals, interpenetrated, truncated by the octahedron and also by the trapezohedron. Good metallic color and luster, perfectly disposed on a matrix of dolomite crystals peppered by tiny chalcopyrite. It is a perfect miniature collected in the 60s, a German classic.

Celestine specimens from Azaila are recognized in the mineralogical world for its beauty, intense color and richness of facets. In the area of Azaila-Lécera we can find good size nodules and nodular levels of silexites. Most of these nodules are compact, but at certain levels appear cavities with gypsum and quartz crystals (sometimes amethyst). In very few of these cavities we can find celestine crystals. Large crystals are usually imperfect. Today it is very difficult to get good specimens from this Aragonese locality.
In this specimen we can see a cavity within the flint matrix in which has developed a faceted celestine crystal. Honey to yellowish tone, very sharp, brilliant and with an exceptional transparency.

Probably one of the best celestine specimens I've seen in this locality. Very aerial, with really good size and showing well defined faces and edges. Honey color, intense with certain zoning and an excellent transparence. Facetted by the pinacoid and various rhombic prisms. The cavity is completely covered by small quartz crystals, brilliant, between hyaline to amethyst. A definitive first quality specimen from Azaila, nearly impossible to find.
