F7 Fluorite crystals from England fluorescent rocks The output of longwave LEDsF7 5x4x2 3 pounds 1. 6 oz from Rogerly England super rich fluorite with amazing crystals. You could use CLR to remove the rust and get deeper green daylight crystals. The whole specimen responds under shortwave or longwave UV even with just sun exposure! Fluorite from this location is very difficult to photograph due to the brightness of the deep purple response.
