Kovdor Massif, Kola, Russia
This is a specimen of the rare mineral kovdorskite, named after the formation in which it is found. The kovdorskite in this specimen is mostly a pale blue, and some of the crystals are sufficiently well-formed to appear nearly transparent and are a deeper celestial blue. I believe that some of the white mineral is also kovdorskite, judging by the similarity in form and texture, while most of the white mineral looks like magnesite (but perhaps it is calcite). There is also a black mineral present, but I cannot identify it.
