The essential contrast of black and white sparks the elegant ambiance of this chess set. White onyx and black marble make a polished expression of leisured dignity, as hand-carved pieces strike poses befitting of such a refined mental exercise. An exceptional gift for the chess aficionado, this set, handmade by the Sierra Family, ranks among our finest. 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).
