These earrings are Hopi work; the gouge-marks in the recessed black areas of the geometric design are clearly visible. They are marked "sterling" but not signed. The hand-wrought flat drops are attached to ear pieces that were hand-set with polished black onyx cabochons. The earrings show fine craftsmanship and are in excellent original condition. They are 2" long and 3/4" wide, and the pair weighs 7.1 grams. They are 30-40 years old.
