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.

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.

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.
