Vintage Cameo Bracelet

I found this old cameo bracelet inside a jewelry box that belonged to my grandmother. It's a carved shell cameo and has a 6 inch stretch band that looks to be gold plated. There are no markings that I can see. I'm guessing that it is a childs bracelet or for someone with a really small wrist. I tried doing some research on it, but found nothing like it so far. If anyone knows anythng about vintage jewelry and can tell me anything about it, I would greatly appreciate it. I would like to sell it, but don't have a clue what it's worth. Maybe it's not worth anything and I should just use it in an art project.
