Vintage Navajo Sterling Silver Turquoise Dangle Pierced Earrings

This is a beautiful pair of Navajo Sterling / turquoise earrings. The turquoise has a very nice green / gold / blue look to it. They have a 2" dangle and the stones measure approx 1 3/8" x 1/2". They are used but in nice condition with light wear. There are no marks that I can see, but they are tested Sterling Silver.
