Chan Luu Turquoise Cluster Ring

Beautiful triple stone Chan Luu silver statement piece ring. Approximately 7 1/4 in size (see pic with measuring tool) . Sawtooth cut around three stones - possibly pyrite stones,not positive, in a deep bluish turquoise green color. Stamped Chan Luu. Unique and hard to find, but just a little too big for me. Excellent condition.
