Thank you! This one is in antiqued brass. I got it in a set of 3 antiqued brass, 3 antiqued nickel at Michael's but I didn't save the package. They didn't have it in regular brass/regular silver or I would have gotten it too. It is 1 1/2 inch across. I think these are similar:http://www.ebay.com/itm/7Gypsies-Cu...ED-PRICE-/281355069615?_trksid=p2054897.l4275 I think you might be able to use a hoop earring as long as the clasp is secure.
I also have some rings in brass and silver I got from ebay.
Thank you so much for sharing that link - I understand what to look for now!
