Another interesting novelty from this part of the southern Republic of Congo are examples of plancheite overgrown by quartz.  In most cases, these quartz overgrowths occur over a more massive, chalky plancheite habit. However, in this case, small plancheite orbs grew on an initial generation of quartz, and were then overgrown by a second quartz generation.  The final result is a much sparklier, sharper looking specimen, and if you look closely in a few areas, you can see the tiny plancheite orbs within the quartz crystals.
