Fuka mine, Bicchu-cho, Okayama Prefecture, Honshu Island, Japan (TYPE LOCALE)
Miniature, 3.6 x 3.2 x 2.2 cm
Henmilite is an ungodly rare copper borate species. The world's best of species by far has come from modern finds at this small mine, about 10 years ago. Before that, only a few museums had even single crystals as good as the 2-3 mm crystals upon this specimen. Briefly, there were enough for all rare species collectors of this beautiful and interesting species. But, that was now a decade ago nearly, and they have disappeared from the market. This is an aesthetic, 3-dimensional piece.
