What can you tell me about this bangle bracelet?

It was $2. No markings, but an area on the inside is rubbed, and a markings may have been there. I believe it's sterling: it cleaned up beautifully with a Sunshine cloth. It runs small, I can barely get it over the width of my had to get it on my 7 inch wrist. It is engraved with the same motif on the outside rim, the side rim, and the inside rim. It has weight. Age? Country of origin? I have not sern another like it. Thanks.
