Obsidian
Obsidian is black, hard, and feels like it was made by a lava monster who had a bad day and turned into a rock.
Text from a friend: My mom’s new necklace is made of obsidian. It’s so dark, it looks like it’s trying to swallow the light.
Caption on an Instagram post: Obsidian is the only thing that could make lava look like it has a soul.
DM from a classmate: I saw obsidian at the museum, and it looked like it was ready to punch me.
