Black Obsidian specimens from Obsidian Ridge, Sandoval County, New Mexico, United States.

Dark black volcanic glass specimens from a famous location.

These are available in various sizes.

Obsidian can be (and is!) extremely sharp and must be handled with care - it is essentially a lump of broken glass, of course. I've used pieces of naturally fractured Obsidian to cut leather, plastics, cardboard, it is sharp stuff.
