This work is made exclusively from North American hardwoods including black walnut, cherry, and mesquite. These are all hard, tight-grained woods which make each board food safe. Sleeping Beauty turquoise is used for the inlay work. To affix the turquoise the stone is adhered with a food-safe epoxy. This adhesive hardens and protects the stone so that it will stand up to the rigors of everyday use. The stone is chosen for its tranquil blue color and lack of black matrix. Approx 10" L x 7.5" W Each board is unique.
