All rings designed by Don Lucas are made with sterling silver and set with gemstones and semi-precious stones hand picked by Don Lucas. The end design is a mix of modern and traditional southwestern jewelry. The rings chosen to show on our website are our latest designs. Some of the rings are one-of-a-kind, while others can be duplicated in any of several sizes. Some of the one-of-a-kind rings can be duplicated, but the center stone may vary a little, especially in the rings with free form center stones.
