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.

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.
