Beautiful material that let's you see the Zincian Pyrite Inclusions in massive Uranjnite. A bit crumbled off in one spot but it is solid and beautiful and priced accordingly! Material like this is rare for the consumer market and it is from only one solid core that survived my experimentation. Use it as a radioactive coaster at your own risk!
