The ring is approximately a size 8, and probably too thick to be adjusted. The central face of the ring measures just under approximately 7/8 of an inch, or about 21.5 millimeters, high, by about 7/8 of an inch, or about 22.22 millimeters, wide. The narrowest part of the band measures just over approximately 1/8 of an inch, or around 3.5 millimeters, wide. (Included is a US Quarter in the photographs, for the measurement-challenged and ruler-averse.) It is stamped inside, "925", and signed perhaps, "WEA", or MEA". Weight is approximately 7.6 grams.
This is a vintage piece, which has been worn and enjoyed. There will be the expected surface scratches and tiny dings in the silver from normal wear. The thick ring remains round and true. Hand polished, but there will still be areas of missed tarnish, especially in the crevices and interior.
A boldy styled, though feminine and curvy, signed vintage Sterling silver dolphin bypass ring. Great movement to the eye, natural and flowing beauty.
