As an ex-pyromorphte collector, one of the more pleasant surprises encountered on this trip were examples of pyromorphite from a few different localities.  In the past, the only Congolese specimens I had seen were old examples of dull hexagonal prisms on a contrast-lacking matrix.  While not the most well crystalized, examples from this location certainly had the most vivid coloration and richness.  Also of particular note, is that the pyromorphite occurs on a malachite matrix.  I suspect this is the same location that also produces the malachite-cerussite combinations.
