Curious globular aggregates formed by numerous fluorite octahedral crystals that have grown together, reaching this globular shape. If you look closely under magnification the specimen you can observe different growing phases. So we can see perfect small colorless octahedra, others as groups of a few crystals sharing faces and symmetry, and some with many octahedrons close to this globular shape. Very fluorescent under SW-UV.
This green color is the best ever found for this site, with transparence and brilliance. They are disposed on an matrix of hard porphyry covered by minute quartz crystals, with calcite and goethitized cubic pyrite.

This area is known as Singuerlín (a neighborhood of Santa Coloma de Gramenet city, close to Barcelona) and from 60's collectors has found these globular aggregates with tones between white, yellow or slightly greenish. Then some specimens were analyzed and labeled as gearksutite. More recent analysis did not indicate the presence of this species but only fluorite.

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).

A brilliant quartz crystals from a well known Catalan area, in the Pyrenees, very appreciated for the quality of its hyaline crystals. A rich group of quartz crystals showing a elongated prism and developed and deformed rhombohedral terminal faces. Transparence and brilliance are excellent, with very well defined faces and edges. They are partially covered by small aggregates of pyrophyllite, between colorless to slightly yellow, with some goethitized pyrite. These specimens usually occur in geodes and it is very common find them falled down inside the vug; this specimen shows that one of the crystals has been lost, without affecting the beauty of the whole. This huge size sample is a nice representative of the known Llavorsí's quartz crystals.

Group of bluish fluorapatite crystals, showing well defined faces and edges. Some of them show defined prism and even hexagonal pyramid faces. Although the site is known, it is not easy to find samples on matrix with a good size and luster ... and on matrix, because it is very easy, when you work them, that crystals fall out. They are transparent to translucent with nice color zoning, more intense in the center of the prism. They are usually accompanied by quartz. In this sample we have a very nice crystal doubly terminated very aerial disposed on the quartz.
