Vintage Avon Medallion Pendant Necklace JP429

Nice vintage Avon medallion pendant necklace possibly early Y2K as it is not in my reference book. Marked on the back NR which is the manufacturer code not the designer initials. This necklace has been misrepresented as being designed by Nina Ricci. She never designed for Avon and most designers had their full name on the back “for Avon”. I’ve had many pieces over the years. Avon has many pieces with NR noted. Do not believe what AI is generating and do your research. In great condition with no missing stones which are bright and clear. The Avon hang tag (if there was one) is missing. The brass chain is 16” with the pendant drop being 2-1/2”. Finished with a good working lobster clasp.
