The specimen shown is a specimen that has a thin layer of yellow Smithsonite crystals covering pseudomorphed scalenohedral Calcite crystals. It's an aesthetic example of a multi-generation pseudomorph with interesting internal crystal structure showing the original Calcite crystals completely replaced with some other species, then Smithsonite covering all.
