Have you seen the Downton Abbey jewelry line at Macy’s? Some of the things are very modern (and ugly, I think), but some of them are quite charming and possibly even useful for historic costume purposes. There are necklaces, earrings, and brooches. Looks to me like the earrings and brooches are the best of the bunch for the most part. However, don’t be fooled by the pictures and do take a look at the measurements of things because the pictures make them look larger than they actually are!
