Limestone rocks often have numerous vugs and pockets where you may find fluorite crystals. Wherever you have a concentrated limestone area, you have a high chance of finding fluorite, especially if the limestone was subjected to hydrothermal activity in the past. Sandstone is another rock where fluorite may be found in.
