Navajo Open Work Necklace in Sterling Silver with Turquoise

Vintage 1970s Navajo made sterling silver openwork pendant and chain necklace. The pendant is set with a single turquoise stone. Measures 2" long. The bail is not original and is not sterling as the rest of the necklace is. If I had an extra jump ring, I would replace it. The Chain is 17" long. Weight: 9.2 grams.
