These rare chalcopyrites really have a lot of variety. The 3.5cm incredibly sparkly main ball is perfectly accented by the 1cm magenta, and blue spheres.

My favorite feature on this specimen is the three ascending perfectly-graded spheres marching up the front of this exemplar Chalcopyrite from this new find!
