Paracelsian is a very rare barium feldspar found in three localities worldwide. The crystals are monoclinic with long tapering chisel points {110} dominating the prism sides. This is the type locality from a deposit "in a band through sandstone and shale, associated with a metamorphosed manganese deposit"......(Handbook of Mineralogy). Old Hugh Ford label.

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.

Small 8mm piece with hundreds of tiny white, bladed Parafransoletite crystals to about 0.3mm. The crystals as you can see are very abundant and very visible and sit on deep red Roscherite. Excellent, extremely rare mineral. Only a handful of these specimens were found in the 1980's. None have been found since.

There at least three tiny crystals of this rare beryllium phosphate on red Roscherite. Impossible to get, this came off of "larger" specimen which was previously sold.
