I came across a piece of really unique spalted walnut too. I made it into an Axiom model. It sports an Osage Orange core with sapele mahogany and walnut spacers. The palmswell is cocobolo with a birch spacer. I added a few extra coats of finish to give it a deeper look and polished them out with white diamond. It created a nice satin finish, yet still highlights the figure of the spalted walnut. It is looking for a new home!
