Time to pony up! How sweet is this statement ring by Zuni artisan Bobby Concho? The craftsmanship is commendable, creating a horse and moon from inlay of turquoise, shell, coral, and mother of pearl. It’s sleek yet striking, a very cool one-of-a-kind piece. Bobby Concho (Zuni). Inlay. Collaborates with Elizabeth Whitman. Mark: Bobby Concho Zuni (etched script)
