Black Obsidian Tumblestones
Black Obsidian tumblestones, available in two sizes – small 10-20MM pieces and medium 20-30MM pieces.
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.
We offer a range of packet sizes, from a single stone to a larger packet of ten.
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.
