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.
