Classic locality

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.

Size: 5.6 x 3.7 x 2.8 cm.
Main crystal: 10 x 9 mm.

The label of this specimen reads "Sevilla". In the catalog of the Manchion collection it is mentioned that this piece of schorl-dravite was acquired to Dr. Joan Viñals, at the Granollers fair in 1988. For that reason, in the absence of more info, we will leave this wonderful Andalusian region as its origin. M. Calvo talks about tourmalines in pegmatites from the Los Ángeles mine, near El Castillo de las Guardas, in Seville.

Gray djurleite well defined crystals (largest group 9 mm) interpenetrated, showing octahedral forms, with triangular faces. On a matrix of copper sulphides. As usual of these specimens, they may actually correspond to phases of djurleite-chalcocite. We can consider the specimens of Las Cruces mine among the best worldwide. From the former Povill collection.

Size: 8.8 x 6.8 x 4.3 cm.
Main crystal: 9 mm. 20 x 18 mm aggr.

Scolecite and aerinite specimens from this small Aragonese town are known worldwide. This specimen shows groups of acicular prismatic crystals those form globular aggregates which, when extracted, they allow us to see the radiated growths perfectly. Snowy white color and good luster. Samples of this quality and size are rare and less nowadays. With Sr. Daunis handwritten label.

Size: 11 x 7.2 x 3.6 cm.

Celestine specimens from Azaila are recognized in the mineralogical world for its beauty, intense color and richness of facets. In the area of Azaila-Lécera we can find good size nodules and nodular levels of silexites. Most of these nodules are compact, but at certain levels appear cavities with gypsum and quartz crystals (sometimes amethyst). In very few of these cavities we can find celestine crystals. Large crystals are usually imperfect. Today it is very difficult to get good specimens from this Aragonese locality.
In this specimen we can see a cavity within the flint matrix in which has developed a faceted celestine crystal. Honey to yellowish tone, very sharp, brilliant and with an exceptional transparency.

Size: 6.5 x 6.0 x 5.8 cm.
Main crystal: 9 x 5 mm.

Curious specimen of calcite from Moscona. Formed by some crystals, one of them predominant, with complex rhombohedrall faces with echeloned growth. Accompanied by tabular barite crystals and on a yellow fluorite matrix.

Size: 8,6 x 7,3 x 4,4 cm.
Main crystal: 28 x 25 mm.

Historically the most representative fluorite specimens from mina Moscona are yellow, recently some of violet tones have been collected. This ancient specimen is one of the few that appeared in the mine with this pink to purple color, with zoning. It is a floater, formed by growths of cubic crystals with faces with polysynthetic growths, very brilliant and translucent. They are partially covered with sharp tabular barite crystals, between transparent to opaque on the outer edges. No damage, good size and fluorescent (UV-LW). A very unusual piece for this classic Spanish mine, from a former German collection.

Very brilliant specimen of arsenopyrite with quartz from this classic Asturian locality. It presents a matrix with quartz and pyrite, and in the cavities several good sized quartz crystals accompanied by small but brilliant arsenopyrite crystals. Spanish classic.

Nowadays, graphite specimens from this classic Asturian locality are very difficult to be found. These specimens show contiguous columns, with greasy luster and defined hexagonal forms. The crystal habit of natural graphite in most cases is determined by its highly anisotropic, layered structure. However, anomalous habits of graphite,determined not only by its structure, but also by the peculiarities of the growth environment, are frequently encountered, and optimization of the space available when solidifying forming columns.
