Small 8mm specimen of one of the rarest minerals around. There was maybe just a few specimens of Parafransoletite that were found at the Tip Top. All chips more than likely were taken from these specimens. Even so, as you can see, there are hundreds of small rice-shaped, thin tabular crystals on this piece. The red is probably a Roscherite member. Pin for scale.
