This is another uncommon penetration twinned crystal from Illinois. It is lustrous and very slightly translucent with a vibrant, deep purple color. Gemmy colorless calcite crystals preferentially cover certain faces of the fluorite crystals which reach 4 cm across. Mined in July 1993 from the northern extension of the Bahama ore body. Ex.
