This is a rare formation in which we can see 3 minerals together: Cavansite florets on Stilbite crystals growing on Heulandite. There are only a few full florets on this specimen, the rest are traces of Cavansites. The Stilbites are very well formed and have a white colour and a pearly lustre.The matrix is made of tiny Heulandite crystals that shine under the light.
