I bought this stone may years ago from Shig and Roy Nagatoshi at an early GSBF convention in Southern California. It was totally natural when I bought it.
The base hasn't been cut. However, I did need to use a rock hammer on the bottom to remove a couple of protrusions so as to make it sit better in the diaza.
