Rough Black Obsidian

Specimen pieces of rough Black Obsidian, otherwise known as 'volcanic glass', sold in 100g packets.

You may receive one piece but it might be two or three - depends on our stock at the time.


If you're planning on lapidary usage, please be aware of the risks. Obsidian is a type of glass and extra precautions should be taken when cutting or forming it. The dust can be especially dangerous.

    I received two respectable-looking pieces of rough obsidian, one a pleasant surprise as it was bigger than I imagined, both perfect for grounding work, which is exactly what I wanted them for. They were exactly as described, with the typical conchoidal fracture and glassy sheen that I expected. It is very rewarding to work with a supplier that knows what they are selling and delivers what they promise!
