Turquoise and Silver Teardrop Earrings

Vintage Zuni style native American Indian teardrop earrings with turquoise inlay and silver rope trim detailing. My mother bought these earrings in the southwest US from an artisan. the back has a mark and initials, but I can't read it. It looks like 22 Zuni but faint. Not marked 925. Either way, these are beautiful and nice wearable size (14/16th inch height and 0.5 inch wide).
