The band measures approximately 5/16 of an inch, or about 7.9375 millimeters wide. The band is just under roughly 1/16 of an inch, or about 1.5 millimeters, thick. (Included you will see a US Quarter in the photographs, for the measurement-challenged and ruler-averse.) It is marked inside, "925", unsigned. Weight is healthy, at approximately 5.6 grams.
This is new old stock ring, never sold or worn, but vintage in from the 1980's. There may be light surface scratches to the silver from years of storage. Hand polished, but there may still be areas of missed tarnish. There will be slight variations, as the ring shown is an example representing the median weight and condition.
A very lovely, well-made, vintage Sterling silver carved band ring. Strong design, heavy and striking. Made the way jewelry was when silver was cheaper. Super fun and very different!
