Old Navajo Tufa Stone Cast Sterling Silver Naja Pierced Earrings

Old Navajo hand poured Tufa stone cast sterling silver Naja earrings. The Najas measure 1 1/8" by 1 1/8". Ear wires are sterling and were replaced by me as the originals were broken. Together they weigh 10.7 grams. Rustic and a rare find.
