Silver specimens from Gualba mines are so appreciated by Spanish collectors due to their scarcity. This specimen shows arborescent and granulated aggregates of native silver emerging from the white matrix of calcite (treated with acetic acid). A unique opportunity to get a silver sample of this historic Catalan mine.

Group of octahedral crystals of fluorite, nice green color, transparent to translucent and very well defined faces and edges. Peppered by small crystals of pyrite with complex shapes and even tabular appearance. They are disposed on a matrix with calcite and pyrite. From a classic Catalan locality. Fluorescence (UV-LW) is red for calcite and blue for fluorite.

On a rocky matrix of granite, partially covered by small but brilliant quartz crystals, some groups and isolated fluorite crystals. Good transparence, brilliance and with a intense green color. A mineral classic from Catalonia.

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. Very fluorescent under LW-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 huge size orthoclase crystals, showing the complex faces. Nice slightly orange color and defined edges and faces. It is accompanied by small crystals of epidote/clinozoisite. It was collected many years ago near of the Montseny massif; this area was well known for orthoclase mineral collectors. A classic from a classic collection. Mr. Daunis and Mrs. Ruscalleda (wife) collection were specialized in Spanish quartz and orthoclase specimens.

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 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 LW-UV. Slight green color, with some transparence and brilliance. They are disposed on an matrix of hard porphyry.

A group of fluorite crystals those, at first glance, seem just octahedra, but if you take a look carefully you will see complex terminations. Some crystals are isolated increasing its aesthetics. Good transparence and intense green color.
This specimen belongs to the "old" fluorites from Berta quarry, from an area of ​​sericitized granodiorite. In the fractures, if it was enough space, they grew lining the walls. When quarry worked lower levels fluorite appeared in fresh granite matrix, but mostly without this depth of color. A great speciemen. A classic between classics of our country.

Group of sharp orthoclase crystals with an orange color. Accompanied by a large group of crystals of albite. You can see the presence of a small group of almandine red crystals. From a classic Catalan locality.

These calcite specimens were found in a pocket in the El Americano (Can Sala) mine-quarries, in the Montseny mountains. This big geode was called "Mercedes" due to the curious color zoning that can be observed at the terminal rhombohedrons faces reminiscent of the German automobile company logo.
Crystals appeared partially coated by carbonated iron oxides and sometimes showed a complex prism, sometimes growing on scalenohedral crystals (like this specimen). This calcite shows a intense fluorescence under UV light. These pieces have disappeared from the market.

Rich group of sharp isolated octahedral fluorite crystals, from translucent to transparent. They show an interesting apple green color. They are accompanied by small quartz crystals. On a granite matrix. This matrix is classic for modern specimens and comes from low levels of the Berta quarry.

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.
