This all handmade sterling silver and Sleeping Beauty turquoise petit point tie tack (or pin) is by Zuni Pueblo artist Donna Valencia. Each small Sleeping Beauty turquoise stone is hand-cut and supported in an individually made bezel, or silver 'sleeve.' Petit-point jewelry is an extremely time-consuming process. This wonderful tie tack is signed by Donna as 'Yatsattie' her married name. About 7/8" in diameter.
