Massive crystallized Apophyllite with a white-transparent color typical of the mineral.
The apophyllite mineral is directly related to volcanism and volcanic rocks, and for this reason it is common to find this group of minerals together with zeolites of volcanic origin.
The piece you receive may differ slightly from the photo shown as the minerals are natural and no piece is identical. The size is approximate.
