EV16H2

Doubly terminated floater. The color is deeper at the terminations, whose luster is also more intense than in the other faces. The crystal grew on other small crystals of Quartz (Amethyst)

TC11P7

On the same specimen there are two very rare species. Kosnarite in pseudo-octahedral, creamy crystals with very sharp and bright faces and edges. The Zanazziite, in very small crystals, has been carefully analyzed and the result is surprising: iron is nearly completely replaced by manganese (thus its pinkish shade), so we present it as manganoan Zanazziite. Matrix is Albite. We’ll send a copy of the analysis to the buyer.

MH26K5

Group of prismatic crystals, a lot of them doubly terminated, of excellent color and with Rockbridgeite crystallizations.

TD6J9

Small spheres and microcrystals of deep red variscite, which is a rarity, intergrown with concretionary formations of violet blue Strengite on matrix.

ME14J9

A crystal of considerable size, very transparent, with excellent luster and a very fine vertical striation.

MC14F5

One can see different crystals that have grown in various directions. To me it looks like it is the very complex crystallization that gives the specimen so many faces, which means that any movement creates numerous reflections. It is a very original floater with zones of smoky color and multi-colored reflection from its interior.

EH13K2

Good miniature. Group of twinned crystals of considerable size for the species and with bright and very well defined faces and edges.

CH98BM7

Spherical group of tabular crystals of blue color, clearer than usual.

PT64P7

The crystals have a curious growth, they are gradually thickening from the base to the top.

EZ66H2

Crystals are distributed as a comb on the matrix. They are transparent, have a good color and show a slight zonation, more intense in the upper termination.

EV86H2

Some crystals are doubly terminated, some others are implanted on the matrix. The aspect of these Mimetite crystals, with its deep yellow-orange color, reminds me of coral growths.

MD96J2

Group of trapezohedral crystals of honey color. On a matrix formed of Orthoclase and Mica crystals.

E91AC7

Cumbria, British Museum, Barite, these are all names that remind me of a splendid past. Jordi bought this one from the Behier collection but did not put it up on the web site as the base has a small ding. But given that you cannot see this defect when you display it and that it is such a nice specimen that displays well I think that it would look good in any collection.

As well as the history I like the fact that it has its old labels and that not only are the crystals transparent but that they have two colors, due, Jordi tells me, to the Hematite inclusions in certain areas which add the red tint.

E56TP7

Group of clear crystals with curious growths and deformations. As strange, transparent and brilliant as the photo shows.

TQ26J2

A nice sample from the discovery of August 2004 in Madagascar, with the typical complex twin and excellent color, luster and transparency.

TM60L2

The crystal growth of this specimen inside a tight cavity makes it different from other Adamites. Formed by two fan-shaped groups of Adamite crystals, nearly perpendicular, this specimen shows marked triangular terminal faces.

TC12N5

The Ojuela Mine is producing neat combinations of Wulfenite and Mimetite. The Wulfenite forms long crystals, which are not very typical for the species, and its presence along with green Mimetite is also something new.

MG63L2

Group of several parallel crystal growths of Azurite, showing the elongated prism and many of them doubly terminated. Excellent brilliance and cobalt blue transparency in the terminations. With a small bit of matrix.

EA10J2

Dense velvet aggregates of acicular crystals of Brochantite contrasting with the deep blue color of the microcrystalline Linarite. On Quartz matrix.

EK64H2

An infinity of fans and needles of Brochantite cover the sample with Linarite, partially covered, on a second plane.

EK10I6

Nice miniature. A group of octahedral crystals of considerable size for the species.

MR64I6

Nice miniature. A group of octahedral crystals of considerable size for the species.

EG7K5

Group of complex crystals with zoned color, deeper on the bevels.

MB63H2

The greenish yellow color in the photo hides a certain zonation finishing in a green nucleus. The specimen is embellished by Pyrite concretions and, especially, by small Quartz crystals, very transparent and rather iridescent.

NB9H2

An open gap in Calcite offers enough space for the growth of Quartz crystals and another pleochroic (different color, black or brown, depending of crystal position) mineral. We acquired the sample thinking it could be something very rare, a sulfide or a cobalt arsenate... As usually happens, the analysis send us back to reality: They are Goethite crystals. Beautiful, very unusual for the locality, but Goethite.

FA7I3

Well defined crystals of good color, contrasting with the greenish-black Heterogenite, on Dolomite matrix.

TE14J2

A taste of the curious globular Elbaites from Myanmar, shaped as “bouquets”, with good color and in white Quartz matrix.

MR62K5

Complex crystals that are forming a bundle, as a consequence of the multiple growth of a multitude of very thin prismatic crystals.

TK14Q2

Sky blue botryoidal growths of Shattuckite. The mining has been abandoned so probably we must expect an increasing scarcity of this kind of sample in the mineral market.

JZ16F1

Very clear and transparent Calcite. The crystals, even though they are on top of each other, show off well the rhombohedral form with many modified edges, which give the specimen a particular softness.

MZ76H2

Translucent and of nice color, the Brookite crystals, incomplete but unbroken, sit on a bed of Quartz and Albite crystals. Some of the Quartz crystals have green inclusions enhancing the specimen.

EE97G6

A perfect design. From a base of Albite crystals a very erect Beryl crystal arises. The prism is striated and ends with a completely flat pinacoid. In fact, the inner crystal is also strongly striated, with some channels, which are hollow to the matrix. The detail picture shows the pinacoid with the mouth of the channels.

NB11M7

A group of two violet crystals, with zoned color and a cluster of small crystals on its side. On the back, there is a neat contact. The crystals have small damage on the edges.

NA11M7

A group of tabular crystals of uniform violet color, with Siderite. The crystals have small damage on the edges.

NC61M7

Floater group of crystals with very well marked color zoning, green on the back and bluish on the front.

NE8N7

The Preguiça Mine is currently well known and the species from there well described. Anyway, an unusual find was made there in 2006, a pseudomorph of Descloizite after Vanadinite. The analysis we did shows only Descloizite but the crystal form is without doubt that of former Vanadinite.

N11EI9

Botryoidal and microcrystalline growths on matrix of this relatively rare phosphate. Its green color is quite variable, darker when more crystalline. The specimen is very rich in Pseudomalachite.

EG89D2

I had to include this fluorite from our recent purchases. Out of all the ones that have recently come from Dalnjegorsk this one stands out for the rare crystal form, its size, and for its good position on the matrix of quartz, galena and pyhrotite. In fact it is perfection and transparency guaranteed.

EK61P0

Telluronevskite is an extremely rare selenide of Bismuth and Tellurium and its type locality is the Vihorlat Mountains in the Slovak Republic. This specimen comes from there, not so aesthetic but extremely rich (for the species).
We will send to the customer a copy of the analysis where Telluronevskite also appears intergrown with the still more rare species Ingodite and the 'common' mineral Nevskite. The description of Telluronevskite was published in 2001.

NA59I9

Sceptered crystal of excellent color and with very well defined faces and edges, on Orthoclase matrix.

NV8L6

Very esthetic Quartz crystal, with very sharp faces and edges. Intense and uniform smoky color and good transparency. Prism faces present fine horizontal striations. On a small Albite matrix. A small gem. Actually it is quite difficult to obtain high quality specimens from Massabé Quarry.

N12FL6

Group of complex Sphalerite crystals with well defined faces and edges, some of them with curvatures. Excellent luster and deep honey color. On a Dolomite matrix, with olive green Siderite. This mine closed a long time ago, and it is now flooded and collapsed, so it is quite impossible to obtain specimens there.

NF8L4

A rosette aggregate of laminar Aurichalcite crystals, with a delicate turquoise color and silky luster, perched on a vug coated by small Quartz crystals with an orange and black layer; and with Limonite that enhances the Aurichalcite contrast. New find from a quarry of the historical Troya Mine, currently flooded and collapsed.

NF56L6

Excellent idiomorphic Barite crystal, with excellent transparency and brilliance. Its upper and side faces have very well marked triangular growth figures that give the edges a sawtooth appearance. Also we can see corrosion and contact geometric structures on some faces. We call your attention on the interesting Chalcopyrite crystal inclusions, where the original yellow greenish color is preserved, while superficial crystals on Barite faces are covered by a thin oxidation layer. The specimen is from mining works of Aizpea, close to the La Troya Mine.

From the mining works close to the Aizpea Mines we offer this specimen formed by groups of complex Sphalerite crystals with curved faces and edges. More than vivid red to orange color. With some small tabular Barite crystals. Really unusual.

NC11L4

Very interesting sample of Fluellite partially coated, on the base, by a thin white layer of Crandallite. The characteristic light violet color is seen and the Fluellite is positioned on a covering of green yellowish Metavariscite in small globular aggregates. All on a black carbonaceous slate matrix. In the deposit one can find Fluellite totally replaced by Crandallite.

NZ9L4

Aggregate formed by transparent Fluellite crystals, with well defined faces and edges, some of them curved. With an excellent brilliance and clearly showing the truncated bipyramidal habit. Some are colorless and others combine yellowish tones. Accompanied by green botryoidal Metavariscite. On a black carbonaceous slate matrix.
