Vintage Jewelry 12K Gold Fill 1976 Engraved Mom Floral Flower Locket Necklace Pendant READ DESCRIPTION. Really pretty 12 Karat Gold filled Mother’s Day “Mom” Locket necklace pendant but it is inscribed on the back with a personal message. I still believe it may be of interest to someone because it just says Mom on the front and the inscription is on the back where no one would see it. Some photos have been enlarged to show detail. Please refer to the pictures for the pictures. In good vintage condition may show minor signs of wear due to normal use and age. Shipped with USPS First Class Mail.
