Vintage Narrow Band Ring in Sterling Silver Size 8 3/4

Vintage narrow band ring with wide reeding. 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.

It still has some sand caught in the grooves. Has smooth wear and some scratching.  Size 8 3/4 and measures 5mm wide. Weight: 4.3 grams.
