This lovely set of slate and shell Go Stones are of the highest grade, and come with their original cardstock box.
The stones are size 31, around 8.5mm thick.
The white stones are Mexican clamshell, and have been cleaned per our Care Instructions. They were soaked in hydrogen peroxide for a week, rinsed with distilled water, then buffed with an iso-paraffin wax. They are Snow-grade, with dense lines that travel directly across the surface of the shell in an even pattern.
The 181 slate stones are slightly thicker and wider than the white stones. They have been washed with soapy watee and rinsed with distilled water. You may choose to buff them with mineral oil for a darker look.
It's preferred to have the black stones slightly larger than the white - if they are the same size, the bright white pieces will appear larger when side by side with the black. Most standard sets will have the black pieces be slightly wider (22mm) than the white (21.5mm).
