A group of green balls of prehnite – the balls are on all sides of the piece. Some darkening in places, where there are dark amphibole inclusions – pargasite has been noted at this locality. The prehnite balls have a nice silky lustre to them – they are not matte as so many are. The colour of this one is quite nice as well. In excellent condition, a few incomplete balls at the periphery. A nice green prehnite with aesthetic form.
