Black material actually looks more like flint or obsidian. It definitely has a glassy texture - and if its not glass and is natural, obsidian would be my best bet. Can you test its hardness?

For the gemstone on the bottom, you mentioned its color changing and I assume that both the stones you posted are of the same stone in different lighting conditions. Is that correct? Please do explain this further. Also the gemstone picture is a bit blurry, so if you can post a better picture that would be helpful.
