An aesthetic and really interesting specimen. Four well-formed cuprite crystals with tiny green brochantite crystals and blue connellite puffballs, sitting on a bed of white smithsonite stained by goethite. Then under longwave UV, you can see a couple of light red fluorescing calcite crystals, and small areas of tiny marshite...
Pale greenish marshite(!) crystal with dark cuprite crystals and white dolomite. The marshite fluoresces strongly red with Convoy UV torch. There are three other areas of the specimen that also fluoresce bright red, but individual crystals are hidden. No doubt about the locality, it is typical of Mutooroo. Width 7.5mm....
