This Fluorite specimen comes from the world famous Diana Maria mine, Rogerley Quarry in Weardale, GBR in the size of 10.0 x 15.0 x 4.7 cm (inventory number #200702). It has a wonderful blue daylight fluorescence and both sides of the plate are crystallized (though the backside has lesser quality crystals). The sheer size, wonderful wet lustre and the amazing twinned crystals along with the octahedral Galenas make this specimen a real treat!
