This is a wonderful floater specimen where a very large single crystal of apophyllite has grown around a smaller one and a stilbite at one of its ends, multiply-terminating around these two crystals. The apophyllite is complete all the way around and has pretty multiple terminations at the other end as well. The apophyllite grades from a frosty white to a more transparent green at the other end. The stilbite is a very faint peach color, and is complete and uncontacted.
