Colorless mostly gemmy and lustrous cubic crystals of fluorite to 1.4 cm on edge across the top of this matrix. There are tiny dark inclusions of marcasite crystals within the fluorite. One crystal along the lower left edge of this piece is cleaved as seen, still very nice. Brightly fluorescent under longwave ultraviolet light. This was likely collected in the 1970s.
