A gemmy fluorite specimen like this piece from the Rogerley Mine is always a treat, and this one is special.  Not only is there almost no damage or dings, the crystals are highly gemmy and are transparent as well.  There are none of the white bubble inclusions that are so common on some Rogerley material.  The crystal faces are highly lustrous and flashy, and are completely transparent so you can look right inside the penetrating twin crystals.  In addition there are some small galena crystals sitting on the matrix amongst the fluorite cubes. The piece is long wave fluorescence.
