These specimens of brochantite from the mining area of Katanga are one of my weaknesses. The long needles of this mineral, filling cavities of the matrix, special green color, brilliance and silky luster... Pure aesthetic. I hope you enjoy it.

Very exceptional group of bastnäsite-(Ce) crystals. Good size, defined faces and edges, transparence, brilliance... And perfectly disposed on a dolomite crystal matrix with talc. A rare opportunity to obtain a top quality specimen of this REE carbonate from this classic French talc quarry.

Druse formed by complex interpenetrated sphalerite crystals, with toasted honey color, some transparence and accompanied by calcite crystals. A huge size specimen from a classic Spanish locality.

Druse of fluorite crystals with a marked color zoning. An intense violet crystal core and colorless in the edges, with some geometrical zoning on some edges. An interesting fluorite specimen. Accompanied by lenticular crystals of siderite. Very aesthetic.

These specimens, novelty, 2014, show very unusual fluorite crystals, with an uncommon color. They show cubic crystals beveled by the dodecahedron and deep hoppered growths. Also almost globular crystals in which the dodecahedral forms predominate. The color is very, very intense, vivid shades that vary between indigo and navy blue, clearly visible when light is incident. We observed also green tones within a few crystals. They have grown on quartz crystals covered by layers of smaller milky quartz. An aesthetic specimen for fluorite and crystal collectors.

After a trip to Morocco in 2013, we analyzed few samples of a mineral similar to mimetite species. Results indicated that it was phosphohedyphane. From the same mine we have obtained some specimens of the zone in which came out in 2013 original ones, but now they showed marked differences. After a careful analysis, results indicate that these were also phosphohedyphane, but with a different shape but similar to the pyromorphite appearance. They are covering cavities of the limonite matrix, small hexagonal crystals slightly barrel-shaped, with green to a yellowish tones. Accompanied by brilliant quartz and vanadinite, some rich in arsenic. It seems that they form part of a pyromorphite-phosphohedyphane series. Analysis results will be delivered to the buyer.

On a thin limonite matrix we can enjoy two aggregates and aesthetic baryte rosettes formed by lenticular crystals are arranged. Both aggregates are complete, but one of them shows an unusual perfection. It comes from a mine known for its ocher tone barytes,but this shape is not very common in this mine.

A stunning corundum, var. ruby, specimen. Perfectly disposed and contrasting with the marble matrix. Very sharp, translucent, brilliance and with a deep pink to reddish color not ususal in this locality. Very fluorescent under LWUV. A perfect gem from Hunza valley area.

Good sized almandine group of crystals, one of them predominant and showing well marked trapezohedron faces. It is not complete, the back side is contacted with the rock. It comes from a mineral area not well represented in collections.

A floating almandine crystal with a good size for the locality. Defined faces and rounded edges (very common), with an intense brown to black color. Acompanied by a interpenetrated minor almandine crystal. A Spanish classic.

A huge size andalusite prismatic crystal, with defined faces and rounded edges. A Spanish classic that many of us have told about and we present here for you.

Good sized specimen of native copper showing complex crystal faces, typical of these specimens, with good color, brilliance and aesthetics. This specimen is from the findings made in the mid-90 in this American mine. It has not been treated with chemicals, so its color and brightness are natural.

Good sized and aerial specimen of native copper showing curved crystal faces, typical of these specimens, with good color and aesthetics. This specimen is from the findings made in the mid-90 in this American mine. It has not been treated with chemicals, so its color and brightness are natural.

A huge size specimen formed by a rich groups of brilliant atacamite crystals, showing elongated forms, intense green color and with transparence. We can observe several clinoatacamite crystals with pseudocubic or hexagonal forms, easy to be identified. Accompanied by scalenohedral calcite crystals, with brilliant quartz. A aesthetic display specimen.

A very aesthetic specimen from Lily mine showing a large group of atacamite crystals, elongated, deep green color, brilliant and transparent. Some of them are included in very sharp gypsum crystals. They are disposed on a matrix coated by light blue crisocola. We have not observed the presence of clinoatacamite. A sample with an elegant presence.

A very brilliant cobaltoan calcite specimen with an intense pink color. Brilliance is due to several small calcite crystals. From a classic Moroccan locality.

In this specimen we can find two of the most interesting species of this Peruvian mine: clinoatacamite and atacamite. The first one is presented as pseudohexagonal cyclic crystals, wiyth an intense green color. Well defined faces and edges and isolated, allowing to observe them perfectly. The atacamite is presented as tabular prismatic crystals, also with faces and sharp edges, bright green. Matrix is covered by brilliant quartz crystals which transparence allow us to see blue tones of the chrysocolla and malachite.

Small group of very brilliant seligmannite crystals, like mirrors, gray to dark brown color. They show well defined faces and edges. Accompanied by needle-like crystals of dufrénoysite, with fibrous appearance and almost black color, interpenetrating with seligmannite. A premium quality specimen for systematic collectors. BOTH SPECIES have the type locality in Lengenbach.
Code: LB 779 (1999)

A really interesting specimen of this uncommon sulphosalt. It presents elongated crystals, one with terminal faces, metallic luster and it is accompanied by brilliant realgar red crystals, some of them grew on sartorite. On the LGB dolomite matrix with pyrite. From this classic Swiss locality, type locality for the species.
Code: L 23.729 (1992)

A very interesting specimen of silver from Kongsberg, a historical European locality. The Bally-Prior Museum, formed by Eduard Bally (1847-1926) in Schönenwerd (Switzerland), contained objects primarily from the fields of mineralogy and meteoritics, but also from zoology, anthropology, paleontology, archeology, and history. The mineralogical collection originally consisted of 5000 specimens from Switzerland and from worldwide localities. The paleontological and archeological collections consisted of over 5.000 objects. The mineral collection grew to over 10,000 specimens. The Bally-Prior Museum was closed due a lack of financing and its collections were sold off at auction in 2003. A portion of the collection is preserved today in the Cantonal Museum of Geology in Lausanne.

Isolated crystal of asbecasite showing different faces and quite defined forms for the species. Orange color is evident. It is disposed on a matrix with clinochlore and albite. A difficult species to be found. This specimen is from the type locality.

Exceptional specimen of asbecasite. Exceptional for the size of the crystals, their color and abundance. They show some defined faces and some of them are partially covered by chlorite and fine needles schorl-dravite. Not easy to find on the market. From the type locality.
