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, and some with many octahedrons close to this globular form. Very fluorescent.
