A rare, excellent and showy thumbnail combination specimen from the Tong Wha (Tae Hwa) Mine of South Korea. A cluster of water-clear, "invisible" fluorite cubes is set in the middle of a triangular matrix of lustrous muscovite books, with nicely framing, off-white dolomite rhombs. This is surely older and very uncommon material from the well-known locale. Ex. Carl Davis Collection.
