Onyx and marble tic-tac-toe set, 'Two Worlds'

Two tones of richly-grained spheres are the playing pieces in this table game, masterfully hand-crafted by the Sierra Family. The spheres and playing board are carved from selected pieces of sectioned marble and onyx slabs. As each piece is sculpted individually with natural stones, there may exist slight variations in the color and grain pattern of the stone. The dimension of the pieces may also vary slightly, up to +/- 1/8 in (+/-2.5 mm).
