This is a very rare combination from the mine, with purple fluorite cubes to 2 cm included by acicular crystals of either stibnite the rare species bismuthinite (some folks say its one, others maintain it is the other: I haven't analyzed). It looks like silver hairs inside the fluorite. So far as I know, this is a unique association to this mine (in either case). The crystals of fluorite are perched on top and form a sharp horizon line, with great sharpness. BETTER In PERSON!
