Fluorite from Riemvasmaak is about the brightest green color of fluorite from anywhere. Here it has crystallized in sharp octahedrons with very good definition along the edges and points.  The crystals are lustrous and nicely translucent (try holding it up the sun to see its neon green color). The deposit appears to be closed now, so top-notch specimens liKE this one, with no damage, are increasingly difficult to come by.
