There are no markings that I can see. I will get my jewlers tool out and see if I can see any smaller markings or names on the clip. I sell antiques, so I know what to look for. These came from an estate sale from a wealthy woman...so they are high-quality....probably 1960's era. I will take some additional photos so you can see how beautiful the stones are and a pix of the back also Thanks for looking.
