Lacy Sterling Silver Ring Size 7 Mexico

Vintage lacy sterling silver ring with an open design. Made in Mexico and stamped with a number 3 eagle stamp. It was made before 1981. Size 7 and measures 12mm wide. 

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.
