Large chunks of beautiful, black obsidian.

Obsidian - also known as volcano glass, is formed when lava cooks very quickly. Obsidian is very hard and breaks with very sharp edges and thus has been used through history for knife blades, arrow heads and even as surgical blades. It's an amazing and very beautiful mineral!

Each piece is unique and will vary in size and shape.

Please note the edges of obsidian rocks may be sharp and should be handled with care and kept out of reach of children and pets!
