Cloisonne Flower

I have a pendant that looks like large locket Cloisonne, how can I find the value of it?

I brought it on Ebay in a lot of assorted vintage jewelry it is round brown background with a flower and a two butterflies on each side of it. There appears to be gold filigree wiring in between the different sections of the design. The pendant is puffy and looks like a locket but is not because it is sealed with gold plating where the two pieces meet. I will try and leave a link for a photo.

well here are some other cloisonne pendants on ebay
since yours is vintage it might be worth a little
more, but it's hard to say.

regardless one of the best ways to try to figure out
how much something is worth is to check for it in
ebay and see what simular things are going for.

appraisels tend to cost too much,
unless it's an antique, or something.

hope this helped!
