Chabazite

This perfectly formed chabazite crystal on volcanic rock comes from a cave called "Planruf", discovery site at "Pufler Loch" southwest of the hamlet of Bulla (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.
