Veins of erythrine appear throughout the sample, sprouting as acicular crystals in the center. The matrix is composed of tetrahedrite, manganese oxides, austinite, and other minerals that are difficult to identify.
Old sample of complex cubic purple fluorite crystals. The fluorite crystals are cubic in shape, with many smaller parallel faces stepped at different levels.
