Rough Black Obsidian
Specimen pieces of rough Black Obsidian, otherwise known as 'volcanic glass', sold in 100g packets or individually.
In some instances, 100 grams may contain 1-3 pieces; however, an order of 500 grams may contain 1-2 much larger pieces. If you require a specific size, please get in touch before ordering to ensure we can supply sized pieces.
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.
Our 100g packets are all natural broken fragments. The offcut pieces are likely to have at least one cut side/edge cut by a diamond saw, as they are offcuts from sphere manufacture.
The pictures you see here are representative of the products and are usually not the exact item you will receive. Where various grades are available we do try to photograph each grade - but some photographs are still on their way!

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!
