...yep you are right it looks like a Jar of Rocks!
It's actually a stand up resealable "jar look-a-like" serving of the Western Australian semi-precious gemstone Prase. It is green in colour and is in a rough state. This means it has not been through any processes like polishing or tumbling. All these pieces are perfect for the mosaic artist. Small, some slivers, mostly thin pieces to add to your mosaics. If you wanted to bring out the richer green of the material, you could paint them with a polyurethane sealer, or use them as Mother Nature intended. :)
The container is about 19cms tall x 12cm wide.
Weighs around 400gms
