Druse of translucent and brilliant hexagonal barrel-shaped pyromorphite crystals. Some of them show parallel growths. With a color zoning that varies between grass green in the center to beige-green on terminal pinacoidal faces. These specimens have been determined by isotopic studies with equal results to those of this mine. This sample is from an old German mineral collection.
In this miniature we can enjoy two sides. One is covered by several hexagonal barrel-shaped pyromorphite crystals. Some of them show parallel growths. With a color zoning that varies between grass green in the center to beige-green on terminal pinacoidal faces. In the other side, small aggregates of transparent and sharp hexagonal pyro crystals partially covered by black coronadite or growing on it. These specimens have been determined by isotopic studies with equal results to those of this mine. Very curious specimen. This sample is from an old German mineral collection.
Groups of brilliant and sharp hexagonal pyromorphite crystals, with a fibrous shape due to parallel growths. Color beige, a little bit green. On a quartz matrix. These specimens have been determined by isotopic studies with equal results to those of this mine. This sample is from an old German mineral collection.
Groups of brilliant hexagonal barrel-shaped pyromorphite crystals. Some of them show parallel growths. With a color zoning that varies between grass green in the center to beige-green on terminal pinacoidal faces. On a matrix of minute quartz crystals. These specimens have been determined by isotopic studies with equal results to those of this mine. This sample is from an old German mineral collection.
A very rich pyromorphite druse formed by several hexagonal shape crystals. Some of them show parallel growths and fibrous like forms. With a marked color zoning that varies between grass green in the center to beige-green on terminal pinacoid. These specimens have been determined by isotopic studies with equal results to those of this mine. This excellent sample is from an old German mineral collection.
A very sharp and complete trapezohedral spessartine crystal. Really nice and uniform color, translucent and good luster. This specimen shows a very interesting gem quality.
These crystals came from a deposit near the town of Loliondo, close to the Serengeti National Park and the border of Tanzania and Kenya.
Two generations of vanadinite crystals. A good-sized brilliant crystals, with echeloned growths and defined faces and edges. With good color yellow and peppered by deep black coronadite globular aggregates. Another generation shows small crystals (<1 mm) but with a nice luster, transparence, and yellowish tone. Both are on a matrix of goethite.
In this excellent specimen we can observe different vanadinite crystals phases. The first is formed by botryoidal aggregates of small vanadinite crystals. Brilliant, translucent and with a yellow to greenish tones. On a second generation, we have huge size and brilliant crystals, with yellow to orange color, which show rounded faces and edges, one of them having a drop shape. One of the cavities of the goethite matrix is covered by very sharp and brilliant lanceolated prismatic crystals of mottramite. Also accompanied bybotryoidal coronadite. Novelty in SMM-2012.
A group of very curious yellowish vanadinite hexagonal crystals disposed on a layer of botryoidal coronadite acicular aggregates which are covering the goethite vugs. Accompanied by small but defined mottramite crystals forming clusters partially covering vanadinite crystals. They show a honey to brown color and dipyramidal faces and skeletal growths. A nice sample to be enjoyed on the display and under the microscope.
A very brilliant specimen of this classic Basque mine. It shows a sphalerite matrix partially covered with brilliant sphalerite crystals, with slightly curved faces and edges. Good transparency and toasted honey color. It is accompanied by several greenish siderite rhombohedral crystals (up to 9 mm.), with some dolomite. A very aesthetic specimen.
Troya Mine was closed in 1993, only a few years before these specimens were collected in 1990. Nowadays the mine is collapsed and flooded. This specimen was in a former German mineral collection since then.
A very nice specimen of this classic Basque mine. It shows a sphalerite matrix with vugs layered by brilliant sphalerite crystals, defined faces and slightly curved edges. Good transparency and toasted honey color. It is accompanied by some greenish siderite rhombohedral crystals partially covered by iron oxydes. Also some minute orange dolomite crystals. Different one.

Excellent sphalerite specimen from this Basque classic mine. It shows a matrix of sulfides covered by several brilliant crystals, with defined faces and slightly curved edges. Good transparence with toasted honey-colored tones. It is accompanied by groups of orange color rhombohedral dolomite crystals. Really representative specimen.

This sample shows two mineralized sides. A first one totally covered by brilliant sphalerite crystals, with complex and curved faces and edges. Good transparence with toasted honey tones. Accompanied by few crystals of siderite. The other specimen side is partially covered by several yellowish-white dolomite crystals and flattened, brilliant and defined rhombohedrons of siderite with greenish tones.

The colorless crystals of fluorite from Emilio mine are well known and show a hyaline transparency. It is hard to capture their brilliance with the camera. This specimen shows a cubic crystal druse with forms of the trapezohedron at the vertices. With some inclusions. Few crystals show small notches on the edges, very common in Emilio fluorite crystals because of its sensitivity to temperature changes, but without affecting their beauty.
A brilliant miniature!
In this brilliant spoecimen we can enjoy some groups of cubic crystals of fluorite with defined edges and echeloned growths on faces. With an excellent transparence and a marked geometric color zoning, from colorless to violet and purple. Fluorite crystals are disposed on a matrix partially covered by small but bright quartz crystals and some tabular barite. An oldie from this mine.
Group of cubic crystals of fluorite, some bevelled by rhombododecahedron, transparent, brilliant, defined and more intense color zoning in the crystal core. Deep violet to purple tones, according to incident light. It is accompanied by quartz and barite crystals clearly visible on the back side. A Spanish classic from a old German collection.
A very rich sample formed by groups of butterscotch tabular thick wulfenite crystals to 9 mm on edge. NIce color, luster and defined faces and edges. This specimen is from an old German collection.
The mine has been exploited for over three centuries. The Miess lead-zinc deposits is one of the richest in Europe. The district has produced the most excellent wulfenite specimens of Europe.
A very aesthetic group of stalactitic goethite-hematite growth showing a very aerial disposition from this classic Moroccan locality. We can observe reddish radiated growths in fractured stalactites on the matrix.
On a matrix formed by corroded quartz crystals, due to chemically aggressive media, are disposed several small pyromorphite crystals of hexagonal prismatic habit, with a extraordinary brilliance, transparence and definition. In addition, its color, almost yellow-green near fluorescent, adds a special touch to this sample. The Daoping Mine has produced a large variety of pyromorphite since ca. 2000 and this is a particular example.
Cobaltoan calcite specimen showing carbonate growths with colours between magenta and yellow, typical for this classic Catalan mine. The mineralization is filling fissures of the Triassic conglomerates. Nowadays mine is partially collapsed and restored and it is impossible to get specimens. This sample is from a previous single finding before shaft was filled and some galleries restored.
A nice cobaltoan calcite specimen showing concretionary growths with a good and deep colour. The mineralization is filling fissures of the Triassic conglomerates, which are very visible in this specimen. Main side shows a polished section where we can enjoy perfectly banded purple calcite and conglomerate individual clasts. Nowadays mine is partially collapsed and restored and it is impossible to get specimens.
