There are two tiny 0.3mm brown spheres of Juonniite. I thought I saw three, but these guys are a little elusive. The blue mineral is probably carbonate apatite. Scandium phosphates are rare. There are only four known: Pretulite, Kampelite, Kolbeckite and Juonniite. There are also two undescribed according to Mindat. Kampelite and Juonniite are the rarest and occur only at this locality.
