This is a natural stone inkstone of unknown origin. It's possibly from Ogatsu in Miyagi Prefecture or Amehata in Yamanashi Prefecture, but I can't say for sure. The surface of this piece displays beautiful striped stone patterns, similar to those found in Ramo inkstones, and I believe it's a very fine piece. Since it's a bit small, I'm offering it at a reasonable price. What do you think of this price?
