The ring is approximately a size 6. The face of the ring measures just over approximately 9/16 of an inch, or about 14.5 millimeters high, and roughly 1/16 of an inch thick. The band narrows in back to about 3/8 of an inch, or around 9.5 millimeters, wide. (Included you'll see a US Quarter in the photographs, for the measurement-challenged and ruler-averse.) It is marked inside, "925", unsigned. Weight is approximately 6.4 grams.
This is a vintage piece, which has been worn and enjoyed. There will be all of the the expected surface scratches and tiny dings in the silver from normal wear. The ring remains round and true. Hand polished, but there are still areas of missed tarnish, especially inside.
A very cool and boldly styled vintage Sterling silver band. Strong design, simple but outstanding detail. Wide and chunky.
