Rosell Minerales

From a find in the area of La Celia mines. This crystal is very rich in faces, doubly terminated, gem quality, very brilliant and with an excellent transparence. It is accompanied by numerous other smaller crystals. 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.

This specimen shows an interesting group formed by a bluish, very bright botryodal chalcedony, which is partially covered by aggregates of calcite crystals, flattened, in axial growth, and with an excellent transparency and brightness. A worthy specimen of this near to disapeared quarry, close to the San Valentín quarry. A very aesthetic piece of this classic Murcia mining area.

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.

Analyzed specimen with report

Tabular celestite crystal with a good size and very defined faces and edges. Very aerial disposed on the matrix. Excellent transparence and brilliance. During many years these crystals were characterized as barite, but later studies showed that they were celestite. From a classic Spanish mine.

Size: 5,7 x 4,0 x 2,3 cm.
Main crystal: 23 x 17 mm.

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.

Group of very sharp barite crystals showing two growth generations. First one is formed by good size tabular crystals and it's coated by second generation. This second growth phase presents stalactitic-shape aggregates formed by bladed crystals and chisel-shaped terminations. With a really good luster and snowy white color. A notable recent find from this Mediterranean mining area that never stops to surprise us.

These are the most fine quality romanèchite specimens ever found in Spain. These botryoidal aggregates show the velvet surface formed by several small romanèchite/pyrolusite crystals (see SEM photo). These specimens has not been treated, only fresh water. Romanèchite shows in fresh fracture the classic grey color. You can observe small but brilliant crystals of pyrolusite on the stalactitic surface. Analysis will be send to the buyer.

On a thin limonite matrix we can enjoy two aggregates and aesthetic baryte rosettes formed by lenticular crystals are arranged. Both aggregates are complete, but one of them shows an unusual perfection. It comes from a mine known for its ocher tone barytes,but this shape is not very common in this mine.
