Perhaps one of the best bracelet and earring sets I have to offer. In excellent condition and very well made. Not a yellow but more like a charturse stone set and surrounded by rhinestone and more charturse small stones. Very dazzling and fascinating piece. Sure to be one of your favorites. I do not see a mark at this time. Gold back. The earrings are clip ons. From the 50s or 60s era and in great condition. Thanks.
