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Each of these tumblestones are polished from fossilised coral pieces, which have been replaced by Agate over the centuries.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