Kolbeckite is a very rare scandium-rich phosphate mineral species (and there are not many such species!). This is from a classic occurrence, and features relatively large spherical aggregates of microcrystals to just over 1 mm in size, nicely isolated and so easily eye-visible. This is, for the material, extremely rich.
