Here is a very fine, very gemmy example of zoned fluorite from Namibia.  The fluorite is crystallized in very sharp cubes with a brilliant wet-look luster.  Inside the crystals are purple diamonds, which are the result of sectoral zoning.  The internal diamond shapes and the color difference are specially pronounced on this specimen, and the thinness of the plate and it's gem clear transparency make them really easy to see. No damage.
