Description: Something about these clams gets me. The polish is great and they are so solid to hold. They have a really aesthetic appeal with all the lines going across, and its instantly obvious they are shells. When you hold them, the heavy weight makes you know its a stone right away. One of my favourites for fossil bivalves.
