     A very aesthetic group of deep green crystals of epidote. Fan-shaped thick prismatic crystals with well defined terminal faces. Just a very few of the terminations are incomplete. Good brilliance and very aerial.

Globular aggregates of prehnite crystals, dull luster and light green. From a Spanish locality not well represented in collections.
Spectacular specimen with a very good size formed by several vanadinite crystals, with an intense red color and translucent. Very aerial disposed on a rocky matrix. Very displayable and unusual specimen.
A scepter quartz crystal with smoky tones, transparence and brilliance. With window growths on rhombohedral faces. Very aesthetic.
Brilliant specimen formed by globular aggregates of orpiment crystals, with good orange-yellow color. They are accompanied by brilliant acicular crystals of realgar with deep red color, transparent and defined. It is accompanied by barite crystals, pyrite and pyrrhotite. A different and quality specimen for this classic Peruvian mine.
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.
