perhaps a form of obsidian with another chemical compound mixed into it, perhaps cordite. or perhaps a cordite that is oddly dark. perhaps it is kyanite.

Hard to tell without any background or properties, and its not one of those minerals that are easily identifiable by visual cues alone. Though the bottom piece doesn't appear natural.

Bottom one looks like glass. The others could be sugilite, but it's rather rare.
