Everything went well with the sale. The items were shipped as expected; good packaging. I was a little worried the charms would be to small for the project I was doing, but they ended up perfect size. The material is definitely stone. It has a good weight to it. I can't speak to its durability, as the back and white pieces are surely glued together, because I haven't had them for very long. I am happy with this purchase. I will buy from this seller again.
