This beautiful and highly ornate example of this classic Jurassic algal fossil would fit into any collection or indeed the interior as it is aesthetically pleasing to the eye. This particular specimen has been cut and ground and a high professional polish applied to reveal the beautiful structure. This stone is locally known as "Beetroot Stone" and I think we can all understand why. Approximately 168 million years old.
This material is now becoming fairly scarse and is well known throughout the world as it is a classic fossil. This thin slice has been ground gem smooth and a high polish applied. The colouration of this algae is due to Boron (Pink).
After a huge amount of hours of preparation to free this sponge from the surrounding chalk block, it is now presented as a stunning three dimensional sponge. The sponge is totally hollowed out and now appears as it would in its natural lifetime. A fantastic addition to any collection.
