Interesting specimen due to the town where it comes from. It is a druse (both sides) of small, brilliant jarosite crystals from this small ballast quarry for railway tracks, located in the area known as "La Corraliza" to the NNE of the town of Vall d'Uixó. With old label from J. Viñals.
Druse of jarosite crystals, very bright and with a characteristic brown color. From a mine little represented in collections.
Doubly terminated quartz crystal of the Compostela hyacinth variety. In a gypsum matrix. It belongs from the former Joan Astor collection (Barcelona). The label indicates locality as Villar del Arzobispo (Valencia), a locality near Domeño.
Good sized specimen with powdered cinnabar aggregates. Intense red color, with an orange point. From this classic mine in Alt Palància (Castelló). For cinnabar locality collectors.
Classic pineapple of hematoid quartz, var. Compostela hyacinth, with good brilliance, complete and in a gypsum crystals matrix.
Very aesthetic group of deep green epidote fan-shaped aggregates on matrix. Epidotes have a good luster and intense green colour. There are some gemmy quartz crystals emerging from the epidote. The original label we will send to the buyer indicates that those crystals are clinozoisite, but recent studies show that all the analyzed specimens are epidote (Calvo, M., Subías, I. (2017): Epidote (not clinozoisite) and andradite garnet from Los Serranos quarry, Cabezo Negro, Albatera, Alicante. Mineral Up, 4:44-47).
Tyrolite specimens from the Amorosa mine are a classic of Spanish mineralogy. In the cavities of the dolomitic matrix we find esthetic and brilliant aggregates of tabular, foliaceous crystals of tyrolite. The SEM-EDS analysis of this sample are consistent with those of other deposits, showing the presence of S and Zn in its composition. It is accompanied by chenevixite, an arsenate of copper and iron, olive green colour. We will send detailed analysis to the buyer.
Celestine crystals from this locality are very appreciated by the collectors of Spanish minerals for their color, brilliance and definition of faces. This specimen shows several celestine crystals of good size, acute, with well defined faces, transparent to translucent and with a visible sky blue color. They are disposed on a matrix with calcite crystals. Nowadays it is not easy to find crystals with this size and quality from this locality.
This specimen shows a very sharp celestine crystal of good size, "lanceolated", with several defined rhombohedron faces, translucent and with a visible sky blue color. It is disposed on a matrix with calcite scalenohedral crystals. Celestine crystals from this locality are very appreciated by the collectors of Spanish minerals for their color, brilliance and definition of the faces. Nowadays it is not easy to find crystals with this size and quality from this locality.
Very rich andradite (var. melanite) specimen, with an intense color, showing interpentrated crystals and isolated ones with a good size. From a classic Spanish locality.
A group of tabular baryte crystals of this locality known for mercury minerals. This specimen, from the Daunis collection, shows us interpenetrating crystals, of good size and translucent. With a small damages, it is an old piece, very interesting for historical baryte and Spanish collectors.
Nice and very interesting aggregates of dundasite needles, a unusual lead and aluminium hydroxycarbonate, from this classic Valencian locality. Dundasite is filling cavities in the goethite matrix. Also accompanied by globular sauconite with an intense yellow color. All of them analyzed by SEM-EDS by Rosell Minerals.
Celestine crystals from this locality are very appreciated by the collectors of Spanish minerals for their color, brilliance and definition of faces. This specimen shows several celestine crystals of good size, "prismatic", with well defined rhombohedron faces, translucent and with a visible sky blue color. They are disposed on a matrix with calcite scalenohedral crystals. Nowadays it is not easy to find crystals with this size and quality from this locality.
Very aesthetic quartz (eisenkiesel or Jacinto de Compostela var.) crystal, showing defined faces and edges, with a good size for the locality. Perfect luster, with deep red color. In a gypsum matrix. From a different Spanish locality than usual ones.

Group of strontianite crystals with an elongated pyramidal habit, forming bundles and aggregates, with color between white to colorless. These specimens appeared in a concrete area of the mine Oriolana (Busot, Alicante) and initially were identified as aragonite or calcite. Further analysis indicated that this was strontianite with some calcium. It indicates that the crystals are zoned and its composition varies within the crystal. They were determined strontianita (majority), celestite, calcite with some quartz (probably due to mechanical mixtures).

Very aesthetic quartz (eisenkiesel or Jacinto de Compostela var.) crystal, showing defined faces and edges, with a good size for the locality. Perfect luster, with deep red color. In a gypsum matrix with another small crystal. From a different Spanish locality than usual ones.
Very aesthetic quartz (eisenkiesel or Jacinto de Compostela var.) crystal, showing defined faces and edges, with a reasonable size for the locality. Perfect luster and some transparency, with deep red color. In a gypsum matrix. From a different Spanish locality than usual ones.
Group of datolite crystals, very rich in faces, translucent-white and well defined. They are on a matrix with calcite and quartz, with some epidote-clinozoisite. A piece of a well-known Spanish quarry from where nowadays is very difficult obtain samples because they are not making new blastings.
A good size crystal of teruelite, a variety of dolomite, from the Valencian cut in the CV-35 road well known for these sized specimens. The crystal shows the rhombohedron, brown and translucent under the light. It is included in a solid matrix of gypsum.
