Black Obsidian Tumblestones

Black Obsidian tumblestones, available in two sizes.

Some of these stones will be slightly brown, rather than a deep black. Some pieces may also have a silver sheen in, which is truly beautiful when viewed in light.

 

These beautiful stones make a great decorative object in a bowl or a small vase. As a glass, they are perfectly suitable for use as fish tank or aquarium gravel. They do not contain any metals or anything that would affect a delicate pH balance.

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.
