While the origin isn't definitively confirmed, based on the stone quality and color, I believe this is a new piece from Duanxi Laokeng. The original box is labeled "Chinese Gold Star Inkstone." This is a truly beautiful and magnificent piece, and from what I can see, it's a flawless masterpiece. It would likely sell for between 45,000 and 100,000 yen in a typical transaction, but I didn't acquire it at such a high price. Therefore, I'm offering it at about one-tenth of the usual price. What do you think of this price?
