The well-known Italian art technique of sgraffito is accomplished by scratching through a material's surface to reveal the lower contrasting layer. Nelson Yatsattie made stunning use of this artistic approach in his approximately 4 1/2" long, 1 5/8" wide and 2 1/8" tall whiskered Bobcat with sky blue turquoise eyes. The lovely intricate treatment effectively emphasizes a furry coat and enhances the beauty of the nicely polished red onyx.
