What a great ring this is! It is a handmade band saw tooth bezel set with an oval vintage bright aqua turquoise measuring 3/8 inch by 1/4 inch. The band is 7/16 inch wide at the top tapering to 1/8 inch wide in the back. The inside of the band is stamped STERLING. This is likely a pre-1970 piece because there is no artist’s signature. The ring is in excellent condition and weighs 3.7 grams.
