| Locality type: | Open-Cast Mine |
| Classification |
|---|
|
| Species: | Fluorite |
| Formula: | CaF2 |
| Comments: | This mine produced some of the finest sea green fluorite crystal specimens in the world.
Fluorite replaces calcite in pegmatitic carbonatites and associated sodic fenites, but also host-rock marbles and biotite schists. |
| Habit: | Cubic (sharp & lustrous) |
| Colour: | Deep sea green to purple |
| Luminescent properties: | Brilliant blue (best LW UV; SW UV). |
| Quality for species: | Excellent - world class for species or very significant. (!!) |
| Abundance at site: | Very common |
