Group of very sharp trapezohedral analcime crystals, good brilliance and with the usual transparency for the species. They are disposed in a cavity of the volcanic rock covered by calcite. Very interesting specimen from a poorly represented locality in collections.

A curiosity that I found aesthetic and mineralogically interesting. Usually the menilite opals are found in a marlstone matrix, but in this case we found it included in gypsum with clay inclusions. A Spanish curious specimen...

Montejícar is located midway between Granada and Jaén, in the northern limit of the province of Granada. This area is known among mineral collectors for the excellent quartz, smoked to morion, doubly terminated and with very poorly developed prism faces, which gives them a characteristic dipyramidal shape. These specimens are found in banded gypsum and marl from the Trias in a Keuper facies characteristic of the Cortijo Cañadas, in the N of the Montejícar municipal district. In the area there are some interesting ruins of plaster kilns.

Druse of trapezohedral crystals of andradite from this classic Spanish locality. Intense brilliance, with colors between brown to reddish. On a granatite with epidote. This is a specimen with pedigree from the Gustav Beck collection.

Main crystal: 8 x 8 mm.

Radial aggregates of ferro-pargasite with an intense luster and very deep green colour. Accompanied in the granatite matrix with epidote crystals and orange calcite. The ferro-pargasite of this deposit is the dominant amphibole in the granatite fissures, although it was classified as hastingsite according to data provided by the exploiting company (according to Miguel Calvo in Minerales de España, vol. IX); for this reason surely the label that accompanies this sample classifies it as hastingsite.

Fibrous aggregate of tremolite crystals, very brilliant and with an olive green colour. They are accompanied by prismatic crystals of darker green actinolite and orange calcite. Good size and representative for the locality and the species. The Manuel-Mercedes open pit is embedded in the granitic intrusions that were accompanied by contact metamorphism and gave rise to the formation of the skarn, with important deposits of magnetite.

Size: 8.5 x 7 x 5.2 cm.

Group of very sharp pyrolusite tabular crystals showing polysynthetic growths, unusual for the species. Good luster, metallic gray color. The echeloned faces gives them a different aesthetics. In the matrix we can observe more classic acicular radiated pyrolusite crystals.
Few specimens were obtained and, at first, it was thought that by their shapes and color tones they were marcasite, but further analysis characterized them as pyrolusite. Probably the best pyrolusite Spanish specimens.

Druse of very sharp baryte crystals showing developed and striated prismatic faces, truncated by pinacoids. The crystals are translucent, and color varies between colorless to yellowish. Excellent brilliance. Similar specimens were classified, many years ago, as hokutolite (a lead-rich baryte variety) but further analysis showed that there was only a minor lead content.

Interesting example of goethite with a richness and very remarkable intense iridescences. From the classic mines of Riotinto; collected in 1985, accompanied by old label.

Size: 9.5 x 7.4 x 3.2 cm.

Arborescent growth of deformed and flattened native copper crystals. Some of them, smaller ones, still show complex cubic forms. Its color is the original and I preferred not alter it by chemical methods. In some of the branches we can see the brilliance of copper, but the rest has this "coppery" tone. It is disposed very aerial on the rocky matrix.
Nowadays the mine is flooded, so get new specimens is quite complicate, if not impossible. A classic mineral specimen from this “Spanish pyrite belt” locality.
