For those who enjoy weird, rare forms. Bright green transparent Fluorites with an exotic structure. These have been called "rhombohedral" Fluorites and they do have that exact shape, even though a cubic crystal should not form like this. These are in fact spinel twinned Fluorites with elongation of the C axis, a distortion that makes this habit. This piece is a cluster of 3 small crystals and one larger all with the habit but the largest one is the center and shows the habit the best. A rare find in one pocket on Hohenstien we are told, that had just a few examples of this form. The color is a rich apple green and the condition is perfect too. Strong display for a small piece.
