In another surprise gift from China to the mineral world, this northern polymetallic mining district in China suddenly started throwing out pocket after pocket of giant crystals of ridiculously rare minerals such as Olshanskyite and Roweite, all best of species by a factor of 100 or more compared to previous known examples of these rare and generally beauty-challenged species. It was literally a flood of rare species specimens....and so they are simply not rare, anymore. Everybody who wants one, can get a nice Olshanskyite (and related things) cheaply and with beauty. However, what will likely stand the test of time best, are the few larger combination specimens with examples of numerous species together - of which very few exist in this size. This particular specimen is aesthetically unique in my experience as it features a sharp, textbook 1-inch magnetite crystal nestled in with the roweite (in super crystals to 2 cm!) and the sparkling white olshanskyite (crystals to 1 cm).
