Classic locality

These specimens are a classic from Las Herrerías mine, and they appeared many years ago. In this piece we can observe a cavity in the rock partially filled with silver foliaceous aggregates, kongsbergite variety, very brilliant and with a silver color with bronze reflections and bluish iridescence, characteristic for the species. This aesthetic and historical specimen has been analyzed and the result will be sent to the buyer. It belongs from the Rolando Gallina mineral collection (Italy).

Classic locality

This is a very good sized specimen of hematite from the group of mines called "Monte de Hierro" (Iron Hill), whose concessions were between the terms of San Nicolás del Puerto and Constantina, although most of the surface is found in the first municipality mentioned. This specimen belongs from the Trigo collection (Mataró) and according to the label it was extracted in 1989 by Julián García.

Size: 9.3 x 7.4 x 4 cm.
Found in ±1989.

These specimens were extracted in Loma de Hamapega (hill), a short mountain range between the localities of Alanís and Guadalcanal. Various minerals were analyzed, among which we highlight conichalcite, green in color, azurite and some earthy aggregates that turned out to be chenevixite. We will send analyses to the buyer. A sample for local collectors.

Analyzed specimen with report

Las Cruces mine, northwest of Seville, is an example of mining in the Iberian Pyrite Belt. But it must be said that minerals those have been found there are not at all common in other deposits of this geological megastructure. Exceptional specimens of chalcocite and djurleite stand out from this mine. This specimen we offer is a magnificent specimen of the latter species, djurleite (an orthorhombic copper sulfide). We can observe aggregates formed by several idiomorphic crystals with octahedral shape and a metallic gray luster. They are disposed on a matrix formed by other copper and iron sulfides. As is usual in these specimens and has already been indicated in previous studies, these crystals may correspond to phases of djurleite/chalcocite. In this case we have carried out an X-ray diffraction that confirms it is djurleite. An exceptional piece, for "gray" mineral collectors, that nowadays is very difficult to get.

Sulphur specimens from Conil (Cádiz, Andalucía) are highly valued among mineral collectors on the Iberian Peninsula. In this specimen we can see various sulfur aggregates, one of them in the form of a dipyramidal crystal. They are disposed in cavities lined with calcite. The banding of the matrix is perfectly observed. A classic locality for fine crystallized sulfur specimens since 18th century. Probably the area has been worked since Roman times. Very difficult to see in the market. Interesting video of sulphur mines from Conil [video].

Classic locality

Pyromorphite specimens from the San Andrés mine in Espiel, Córdoba, have been known since the first half of the 20th century. At the beginning of the 80s of this past century several quality specimens were recovered from the mine. This specimen, due to the date on the label of the J. Astor collection (Barcelona), can be dated to this period. The specimen shows several pyromorphite crystals, of good size, brilliant, translucent, thick and with shapes of the hexagonal barrel shaped prism, with the characteristic color between green to yellowish-green. They fill a vug in the goethite matrix. A Spanish classic.

Classic locality

his good sized specimen from the late 80s belongs from the Arguijo collection, and it was mined in this famous "onubense" mine. It is a sulphide matrix partially covered by brilliant covellite microcrystals, very defined and visible. It has an intense metallic blue iridescence and this very characteristic color. It is accompanied by numerous crystals of native sulphur with curved faces, brilliance, translucent and showing a delicate yellow tone. It was mined from a sporadic finding in the Corta Atalaya, Minas de Riotinto. A unique occasion to obtain one of these "old" specimens.
