Unusual Chalcopyrite tumblestones, an ore of Copper. Being a metal ore, this is very dense and heavy, and quite hard to cut, too – the tumblestones are quite angular rather than being smooth and rounded as you would expect.
These stones are not suitable for use in a fish tank, aquarium, or anywhere especially damp. This is because they are a metal ore, and could potentially leach chemicals into the water.
For more information about Chalcopyrite, and a full list of all our related products, please see our ‘Chalcopyrite’ section.
If you’re not sold on the stone, we do sell a wide range of semi-precious tumbled stones.
