This is a rare formation in which we can see 3 minerals together: Cavansite florets on Stilbite crystals growing on Heulandite. There are 3 bigger Cavansites and over 10 tiny Cavansites on this specimen. The Stilbites are very well formed and have a white colour and pearly lustre.The matrix is made of tiny Heulandite crystals that shine under the light.
