Calcite and Plattnerite on Wulfenite

A high quality specimen of the coated wulfenites that came out about 6 years ago. The blades are almost entirely caoted with white, chalky calcite on which a dark dusting of platnerite occurred. Close examination reveals tiny red blebs of what is likely minium and some prismatic brownish crystals of what may be fornacite.
