This is an example of the "Picasso"method of jewelry design (Tanya Veit). It is made by full fusing dicro face down, and then carving out Zentangle patterns with small diamond drill bits and a Dremel tool. You then bevel the edges with the lap grinder and the fire polish to reestablish the glossy finish. I will admit it does takes some practice, both finding a comfort level with Zentangle and developing a steady hand with the Dremel, but well worth it. It really adds variety to my jewelry ensemble.
