Vividly zoned light lavender purple fluorite with a blue core. Lustrous surface texture and well defined mosaic overgrowths. In excellent condition. Acquired from an Ozark-Mahoning mill employee who claimed to have "picked it off the belt", however the pristine condition of this specimen lends some doubt to this claim.
