A large fluorite specimen from one of the lesser known Ohio fluorite localities--the Bluffton Stone Co. Quarry. This quarry operated since at least 1910, though these were discovered by a field collector in 1996-- I have no idea if the quarry is still operational.
Either way, this is a rather good cabinet sized example for the locality, with Chun of sedimentary rock hosting a nearly complete vug of yellow and purple fluorite crystals.
