Spider Web Obsidian Tumblestones
Spiderweb Obsidian tumblestones, an unusual variant of Obsidian with various impurities causing a mixture of blue, grey, and black colours.
This is likely as close as we will get to selling a natural blue Obsidian. These are larger tumblestones, mostly around 30-40MM long each.
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!

What are tumblestones?
Tumblestones are stones that have been put in spinning barrels with an abrasive compound for weeks or months. This slowly rounds off the rough rock and corners – the stones are then cleaned, and placed with a less abrasive grit. This happens several times until the stones are placed into a barrel with a polishing compound for their final polish.
