Wavellite with Quartz Chalcanthite This is confirmed HubneriteAlthough Wavellite is a fairly well known phosphate species, it is truly only found in a handful of localities in well crystallized display specimens. The majority of the Wavellites from world localities feature either micro crystals, or incomplete (broken) spheres on matrix. The Bolivian Wavellites, particularly those from the famous Siglo XX mine, are among the best in the world due to the fact that they occur with eye visible spheres that are often
