Chalcopyrite Tumblestones

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.

    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.
