Yunzi Double Convex Go Game Stones and Bamboo Bowls Set - 9.2mm (Size 33)

This is a set of Yunzi professional Go stones, China's finest. Yunzi stones are beautiful to look at, carry a nice heavy feel, and possess excellent 'snap' qualities. The stones will actually look nicer over time as they absorb moisture and natural oils from your fingertips. Yunzi stones have been made for almost a thousand years in the same area of Yunnan Province in southern China. The secret recipe for making them is closely guarded, and nobody outside of Yunnan knows for sure what they're made of - although rumor has it that the ingredients include agate and Yunnan mountain stone mixed with agate. To make sure that stones are genuine, hold them up to the light and you will see a greenish halo form around the edge. This is a unique characteristic of Yunzi. The texture, symmetry, and precision of these Go sets is captivating and sublimely captures the essence of the game. If you haven't played with these stones before you'll find it to be a completely different experience than playing with glass or plastic stones. The stones have a balance and deep coloring that is instantly noticeable and leave an audible "snap" as you place them on the board.
