This set came to Baduk Club from a reseller in Mie Prefecture. Agate and Onyx are a popular choice in China, where this set probably came from originally.
The white pieces are agate, with some variance in color. The black are onyx. They are about size 36 (10mm) thick, but will have some variance in size because such stones cannot be cut with as much precision as slate & shell. They were not counted, but they fill the bowls very snugly so it is likely a complete set.
The go bowls are Marble, with nice lids cut to match. They are polished on the outside but may be rough on the interior - see the photos for details. One lid appears to have been broken and reglued.
The board in the photos is not included.
This is a Vintage product.
