If they make a slightly different one, just kind of the same style, and now they've listed your exact bracelet, unless they're using your photos, there's probably nothing you can do. If you report them as non-handmade, Etsy may investigate, but all they will have to do is prove they have the supplies and ability to make the bracelet, which, if they make the same kind of stuff as you, they probably do.
I don't know why they'd do that, though - unless they've marked it up a lot, it seems like not a good money-making scheme, buying things retail (and paying shipping!) and then selling them retail.
