Nikischerite is the iron-rich analogue of (manganese-rich) shigaite, discovered only recently. It is named for American mineralogist and mineral dealer, Anthony J. Nikischer (b. 1949), who first analyzed the mineral. At the same time that he had gotten specimens of this new find (late 90's), so had dealer Brian Kosnar through his family's longstanding contacts in Bolivian minerals and they were also looking at this as a possible new species but had not the work done as yet. I bought specimens from both at the time. Really, there wasn't very much available in total - the problem was that Nikischerite looks a whole lot like substandard ludlamite and we suspect most of the pocket was thrown away or sold AS ludlamite! Funny enough, Tony had more specimens overall, but the Kosnars had obtained several unusually large specimens from the find (all the pieces I bought from Tony then were thumbnails); and this is one of the two miniatures I had obtained from Kosnar at the time, perhaps 10 years ago. I sold it to a collector from whom I recently exchanged it back as his tastes shift to larger rarities. This remains the largest good specimen of Nikischerite I have seen aside from one specimen he kept, which Tony showed me way back when, and I was happy to have it back
