Though incomplete and showing considerable damage, I think that this is one of the more interesting Opal specimens that I have seen. It consists of most of a clam, with both shells set against each other so that the clam is "closed". These shells have undergone fossilization, and have thus been opalized. All of the clam's outer edge and a portion of one of its other sides is missing; however, this enables one to clearly see the glowing, purple iridescence that one of the shells possesses. The curved striations that line the surface of each shell are heavily worn, but still visible in some places. There is a depression between the shells along the clam's outer edge that is packed with a soft silt. I am tempted to do a bit of careful work with a pick to remove this silt and see how hollow the clam is.
