A top example of purple fluorite from Inner Mongolia.  To begin with, purple fluorites have been somewhat uncommon at the locality-- the vast majority have been colorless.  Unlike the majority of purple example that have been found, this one has smooth, lustrous surfaces (not etched!) and great color-- simply holding it beneath a ray of sunlight causes to piece to glow.

The back is etched, but there is no significant damage to the piece.  In a couple spots, very minor micro chopping is visible under magnification.  I have photographed the piece under strong lighting, as it would be in a display case  It does not take much for the piece to completely light up.

For its form, lack of damage, smooth ( and not oiled!) surfaces, and most of all, because of its depth of color, I consider this to be an exceptional piece.
