Nikischerite!

 A small group of very rare Nikischerite specimens.  This species is the iron rich analogue of shigaite, and was first described in 2001 from specimens produced during a single find that occurred in 2000.  At the time, there were estimated to be fewer that 200 specimens in existence— this recent find only bumps that up by a very small number. Usually news of new mineral species tends to go under the radar, but perhaps because the name was selected honor a prominent mineral dealer, and because the crystals were actually visible (versus the usual microcryalline smear-on-matrix that new species tend to be) this one actually received quite some attention.

It is worth noting, that virtually all of what was found originally were thumbnails. The cabinet and miniature pieces on this page are truly exceptional, rich examples of the species.
