Yunzi Double-Convex Go Stone Set

Each set includes 181 black and 180 white stones, plus 6 extras (3 of each color).

Key Features:

• Durable Ceramic Construction – Fired at high temperatures to create dense, chip-resistant stones built for years of regular play.

• Premium Feel and Weight – Smooth matte texture with a solid heft. More comfortable and less slippery than glass or plastic stones.

• Signature Sound and Appearance – Black stones reveal a subtle green glow under light. Both black and white stones produce a rich, satisfying snap when placed on the board.

• Standard Size (9mm x 22mm) – Double convex shape, crafted to professional dimensions. Suitable for full 19x19 play.

*Hand-measured—Size may vary ± 0.5mm

*Air bubbles are an inevitable part of the manufacturing process and do not affect gameplay. If you prefer flawless stones, check out our New Yunzi, which features a thicker build, no air bubbles, and a dark blue translucence under light.
