Navajo pearls (oxidized sterling silver beads) with genuine Kingman turquoise beads. Sterling silver clasp. A classic southwestern look. Go ahead and wear your hair up - this necklace is just as pretty from the back with two turquoise beads by the clasp! Great to layer or wear alone. The pearls are 5mm. They are sterling silver - not plated. The turquoise beads are approximately 6mm and 7.5-8mm semi rounds and an approximately 10mm potato shaped bead.
