This set came to Baduk Club from an antique dealer in Hyogo. Agate and Onyx are a popular choice in China, where this set probably came from originally.
There are 181 onyx pieces (black) and 180 agate pieces (white). The agate have some variance in color, which is typical of that mineral. The black are onyx.
The stones are standard width, about 22mm, but have a lot of variance in thickness. It is difficult to cut such stones with exact precision.
Please see the photos for sample measurements. The board is not included.
