The colour and transparency of this small cabinet-sized Fluorite from Ozark-Mahoning mine, Cave-in-Rock, Hardin Co., Illinois, USA is exceptionally fine. Infact, I would say that this outweighs the few areas of contact damage seen on some of the corners of crystals. Side-on, the Fluorite presents very nice layered colour zoning from grey/white internally to progressively darker purple outwards to the terminations, but in discrete bands. Front-on and back-lit, wonderful darker purple 'lines' can been seen internally, providing a shadow outline to the external crystal form. The front facing crystals, despite some being damaged on the corners, display a superb tessellated pattern and a really fine glassy lustre. Ex Arvid Pasto collection, no. AEP1802.
