Vintage Sea Turtle Band Ring in Sterling Silver Size 8.5

Vintage narrow band ring in an openwork sea turtle design. It is a size 8.5. Measures 5mm wide. Weight: 1.9 grams. 

 This came to me from a man that found a large amount of rings on the beaches of Mexico and Southern California with a metal detector. The majority of them are from the 1970s and early 1980s.
