Thanks to a Jewelry on Etsy Team friend, I recently discovered bonanzle.com. It's similar to ebay, but offers more options to buyers and sellers alike, along with very low seller fees. I liked what I saw, so I signed up to sell my jewelry on bonanzle.
Unlike etsy, you can sell all sorts of things, not just handmade, craft, supply, or vintage items. It kind of broadens my horizon, I think. If you haven't bonanzled yet, give it a try!
