I am at no means a professional, I’m just selling my grandmothers items from her storage units, I don’t have time to do research it’s looks to me like Vintage Hand Painted Glass & Clay Beaded Necklace 24”, See pictures one of the white pieces has little brown spot, I do not clean any of the jewelry because i’m knows to ruin it somehow. It comes as is. This is a beauty. If you need more pictures i’ll be happy to take them
