This is an old Tang inkstone (similar in texture to purple Duan stone), known as a high-grade calligraphy tool. The stone surface is a deep, calm purplish-brown, and it grinds ink very smoothly. Natural "furu" (boiling-like patterns) and transparent stone patterns speak to its high quality. A very high-grade dark wood box is used. The outer box has stains and dirt, but this is also a high-grade item originating from China. The ink grinding surface shows patterns inherent to natural stone, and the inkstone rim features elegant, hand-carved patterns characteristic of an older era. A cloth-covered tomobako (matching box) with a distinctive atmosphere is also included. This inkstone is recommended for both collection and practical use. It is a piece that possesses a definite presence and dignity. There is no noticeable damage, and overall, it is in very good condition for a used antique inkstone.
