Tumbled Agatised Coral

Collectors will love these medium sized pieces of tumbled Agatised Coral, which measure approximately 20-30MM in length.

Each of these tumblestones are polished from fossilised coral pieces, which have been replaced by Agate over the centuries.

Maybe they would make excellent display stones in a bowl or a small vase? Because of their nature, in fact, they almost seem like the ideal decorations for a larger fish tank or aquarium.

You can buy these stones in a range of packet sizes, from a single stone to a packet of ten.

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.
