Obsidian's origin is different from the most other natural stones, slowly built by mineral crystals. Obsidian is born in explosions, fire and lava, it is a volcanic glass without any crystal structure.
Note: the image gives you a good general idea of what the cabochon looks like, but colors and patterns of natural stones may vary from lot to lot.
