Geology & Origin

Fluorite commonly forms in hydrothermal veins and cavities, where fluorine-bearing fluids precipitate the mineral. Namibia is known for numerous Fluorite occurrences showing a variety of colours and colour zoning. The purple colour is influenced by structural defects and trace elements within the crystal lattice and can vary considerably within a single piece.
