Aesthetic group of well-developed baryte crystals from this Murcian locality. They are disposed forming a "open-book" shape with parallel growth. They stand out as being covered with small, bright and transparent crystals of calcite, some chalcedony, peppered by small crystals of goethitized pyrite and manganese oxydes. A piece of an unusual locality not easy to find in the mineral market.

Interesting matrix: A very esthetic and representative piece from this classic Spanish locality were nowadays is forbiden collect minerals.
This locality is located in La Celia volcano where we find remains of a volcanic neck (chimney) and streams from Pliocenic age (1.8 - 5 million years). These mines have a special geological interest, as they contains an exceptional locality for fluorapatite in the volcanic rock "jumillite". Jumillite is a volcanic rock of the lamproite group, a variety of phonolitic leucitite, consisting essentially of diopside and leucite and, to a lesser content, by olivine, alkali feldspar and phlogopite.

It is accompanied by green botryoidal aggregates of conichalcite (mainly in back side) and some azurite. Also yellowish spherules of arsencrandallite and brown yukonite. Lavendulan from Pastrana has been famous for its intensity of color and its crystallization.

Cronstedtite is a rare iron silicate of the kaolinite-serpentine group. This is a good representative of the cronstedtite specimens from this classic Spanish mine. It shows a lustrous, black, trigonal crystals forming groups on the matrix. It is a rare oportunity to get good specimens of this species.

Size: 5.0 x 3.8 x 3.5 cm.
Main crystal: 8 x 4 mm (aggr).

In the matrix of goethite we observe several cavities covered by small brilliant crystals, gray metallic luster; once analyzed results indicated to be hydrohetaerolite. We discuss whether it is hetaerolita, but analysis carried by Joan Viñals indicated the hydrated form. Under the SEM-EDS, tetragonal dipyramids are observed. It is accompanied by calcite crystals and hemimorphite (tabular crystals in book shape). SEM-EDS analysis will be sent to buyer.

Size: 7.3 x 6.4 x 6.3 cm.

Group of interpenetrated cubic fluorite crystals with violet tones and delicate color zoning, transparence in some crystals, most being translucent. Characteristic for fluorite of this mine are the corroded faces. They are disposed on a matrix of iron oxides. What I also would like to emphisize of this piece is the mine from which it comes, near Alumbres in Cartagena, not well represented in collections.
