I took lots of photos so you can feel how it interacts with light. I propose this instead of bismuth in small showcases made of wood and glass. While they also look good, I had a crack on the bottom edge of the display which didn't look good. In addition, this piece is larger than the one on display. Note that this material is very fragile and will break if dropped. Even small pieces can easily break off when handled, so be careful. Very nice, I recommend.
