Looking for something special?
While we try to stock a large choice of gemstones, minerals, and fossils, we cannot keep everything!
If you’re looking for a special piece that we do not have in stock, or isn’t listed on our website, please feel free to contact us – we will try our best to find it for you. We have a network of contacts around the world in wholesalers and lapidary workshops, and can source most items at a fair price.
