Artfire.com is another kind of like etsy
I buy a lot of jewelry from Ioffer.com It is like ebay but more relaxed and they don t have the high fees that other websites do. Have several friends with stores there and 4 sell a lot of jewelry from their stores.
you can also try in ecrater.com but unlike ebay and etsy you will not pay any listing fees in ecrater which is good.
See if vivre.com will buy it. I buy from there alot.. Very unique items...
