Go stones come in different materials and sizes, which determine the stones’ appearance and feel. The finest stones are made from natural slate and clamshell, as they have been for hundreds of years. Choose the thickness that best suits your taste. For purposes of economy, most players use glass or ceramic stones.
We offer several different thicknesses to fit your taste and budget. S210/S211T stones are slightly (10% or ~2mm) smaller in diameter than the other styles. The thicker stones are more uniform in appearance than less expensive stones.
Slate and Shell Stones are cut from black slate and clamshells as seen here. The thicker clamshells are the hardest to produce in quantity (and hence their price).
