About this item: 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). About our Artist: Odette Sierra of Mexico and her father, Edgar Sierra, opened their workshop 30 years ago. Submerged in this artistic heritage, the Sierras began crafting parquet tables in onyx and marble. The art of sculpting marble and onyx demands patience and virtue, both of which have been cultivated over time in the Sierra Family workshop.
