Sterling Silver Vintage Geometric Dangle Earrings

Sterling silver vintage square geometric design earrings. The pattern is a central circle surrounded by a square with dots and lines. Dangle style with an earwire attached to a loop. I don't know the exact origin, but can be identified with Native American or Hopi silver. Stamped 925 on the back. Each earring is 1/2 inch on all sides. Length from the top of the loop is 1 and 1/4 inch. Nice and lightweight. Each one weighs 1.6 grams. Great condition.
