Raw Black Obsidian Chunk - Natural Volcanic Glass

Obsidian has a different story from a conventional crystal: it is naturally occurring volcanic glass. Left rough, this Black Obsidian chunk shows the uneven surfaces and fractured edges that make the material interesting to examine up close.

Add it to a geology collection or contrast its raw texture with polished stones in a display. This is a substantial rough piece rather than a smooth pocket stone, so handle it with care and choose a secure place to keep it.
