For your consideration are these nice, very well made genuine turquoise sterling silver screw on drop earrings. I believe they are circa 1960s and Native American in origin. The craftsmanship is exceptional.
Each earring measures 1 and 5/8 inches by a hair under 5/8 inches across.
They are fully functioning and un excellent condition with no damage. The patina is a little uneven on back and I think these were cleaned. The turquoise is smooth and undamaged with a small bit of natural matrix.
