Brightly lustrous gemmy green daylight fluorescent crystals of Fluorite from the Heights mine, Weardale, Cumbria. Fine interpenetrant twinned crystals of Fluorite measuring to 2cm on edge are a richly inter grown formation on the display face. The matrix is a typical altered iron rich Limestone matrix. Since the very early 1980's it has not been possible to access the underground workings of the mine.
