I believe these earring were made by Navajo artist Wilber Wauneka. They are signed WW Sterling and my Native American Hallmarks identifies two artist with this mark but when I searched the web it was Wilbur that made both inlay, overlay and traditional Navajo designs, where the other WW artist just made heavy traditional designs.
At any rate these earrings are beautiful. Made in geometric triangles with inlay geometric patterns, The artist used turquoise, jet, coral and mother of pearl.
