Group of octahedral crystals of galena, well defined, some vertices truncated by the cube. They are disposed on a brilliant matrix covered by twinned marcasite, small rhombohedral crystals of dolomite and sphalerite with a honey color and transparence.
A sample from a classic Spanish locality. Old specimen, so the stability can be ensured.

In this sample we have a complex twinned escalenohedron group, "doubly terminated", with combination with the rhombohedron. Transparence is excellent, with defined faces and delicate edges.
These specimens appeared accompanied by pink dolomite, at level 6 of this mine. An excellent miniature from this classic Spanish locality. Calcite specimens from la Florida mines are known and valued worldwide.

Perfection! A nice crystal of vivianite, with a deep green color and well defined. With transparence that show the green tone characteristic for the species. Very aerial disposed on a solid sandstone matrix, sulfur free which ensures the stability of the specimen in the future. It is better in live than on the photo, but enjoy them. An exceptional specimen.

No, it is not a Spanish aragonite, it is French. This specimen shows various crystals twinned and interpenetrating each other. They have a good brilliance and some transparence and color varies between from brown, reddish to colorless. With small red quartz crystals (Jacinto de Compostela), giving it a distinctive touch.  Dedicated to aragonite collectors.

Peppered by small red quartz crystals (Jacinto de Compostela), giving it a distinctive touch. Huge size. Dedicated to aragonite collectors.

These doubly quartz crystals with amethyst hour glass color zoning never are always amazing. In this specimen we see this internal color zoning and delicate and thin brown filamentous inclusions. Defined edges and faces, of course. To increase its interest, one could see some faces of the prism and rhombohedra with opalescent dull luster, while other rhombohedral faces are completely transparent and allow us to see clearly the geometric color zoning inside the crystal. On the back shows usual for these specimens recrystallized contact. A specimen to enjoy crystallography and aesthetics.

Specimens of this Australian locality are uncommon in the maket, but their beauty makes them stand out from the smoky quartz samples. It is very curious how these specimens nodules are found into rhyolitic matrix geodes called "thundereggs"; this vugs are usually covered by small milky quartz crystals, some amethyst... They are in themselves a treasure of Nature. In this specimen we see a group of very defined crystals, one doubly terminated. Excellent transparency and smoky color zoning. On matrix. A very aesthetic and elegant piece.

Floater formed by of complex group of vanadinite crystals showing parallel growth with curious hoppered forms to add interest to this specimen. The color varies from orange, reddish to beige. The luster is excellent. A small nick that doesn't affect the overall aesthetics. Rare are these crystals of this classic Moroccan mine, uncommon...

A very rich group of prismatic crystals of ferro-actinolite of intense green, near to black color, brilliant, defined, with flattened terminal faces and some with pyrite on them. Aesthetics is excellent and the vertical disposition of the crystals makes this piece a different sample.
They are disposed on a matrix of albite with several rounded and brilliant magnetite crystals. Also with small pyrite with complex and interesting forms. This specimen is an excellent representative for the species and more, if possible, for this Spanish locality.

On a rocky matrix of ophite we can enjoy several groups of fan-shaped epidote crystals. Intense green color and excellent brilliance. Prismatic crystals show flattened terminations. Acompanied by a layer of needle like actinolite crystals, fibrous and with a green bluish color. Specimens combining both species are uncommon because many times collectors clean specimens with water and eliminate this delicate formations. From a Catalan locality, a huge size and different aesthetics specimen.

A specimen very rich in aggregates of acicular prismatic  pyromorphite crystals with an uniform green color and silky luster. On a quartz matrix. A French classic from old "times".

This specimen shows a rich group of lanceolated austinite crystals with an excellent transparence and brilliance and a slight greenish tone. They contrast on the goethite matrix layered by several sharp adamite crystals, defined, brilliant and with a yellow to orange color. A sample with aesthetic and mineralogical interest for the quality of the austinite and its paragenesis.

This speciemn shows various aggregates formed by several austinite lanceolate crystals. Good transparence, excellent brilliance and slight greenish tone. On starkly contrasting matrix with goethite-hematite. This specimen has a good quality for the species. I recommend the buyer to use a magnifying lens to enjoy the small crystals that are disposed on the matrix. Enjoy it!

This nice speciemn shows various globular aggregates formed by several austinite lanceolate crystals in radial growth. Good transparence, excellent brilliance and almost colorless, they are real gems. On starkly contrasting matrix with goethite-hematite and small crystals of adamite. This specimen has a superb quality for the species. I recommend the buyer to use a magnifying lens to enjoy the small crystals that are disposed on the matrix. Good choice.

In this double specimen we did not want to separate the two parts because symmetry gives them a very nice aesthetic touch. We can observe nodular aggregates of variscite. The green color is very intense. They are embedded in a type of silicified breccia matrix with iron oxides. Both are polished in the front side (which allows us enjoy the structures) and natural cut in the back side. To find samples of this quality you must go back to the past times.

In this double specimen we did not want to separate the two parts because symmetry gives them a very nice aesthetic touch. We can observe nodular aggregates and possible tigmatic folds in the veins of variscite. These meandering folds are caused by the flow of a viscous fluid into a more fluid media. The green color is very intense and it is combined with whitish and yellowish areas. They are embedded in a type of silicified breccia matrix. Polished in the front side (which allows us enjoy the structures) and natural cut in the back side. To find samples of this quality you must go back to the past times.
