Chabazite

This perfectly formed chabazite crystal on volcanic rock comes from Planruf,  discovery site at Pufler Loch southwest of the hamlet of Pufels (Bula in Ladin). The mineral, named Puflerit after the hamlet, is a variety of stilbite with whitish-yellow, drop-like shapes, smooth and shiny on the outside, with a radiating pattern on the inside.
