Southwestern Necklace Set with Sugilite Pendant

This necklace has the best the Southwest can offer, with turquoise, purple spiny oyster beads, and the sterling pendant has purple sugilite inlaid with opal. Necklace is about 17" and the pendant adds another 1 3/4" drop. Pendant is not stamped, but earlier silversmith work was not always stamped. Tested with jeweler acid to be sterling silver. Vintage. Pendant is lightweight, so this is not a heavy turquoise necklace. Includes matching earrings. See last photo.
