Vintage Mother of Pearl Pink Classic Rectangular Clip Earrings Description * Elegant Vintage Mother of Pearl Classic Rectangular Clip Earrings. I am not sure if these are Faux mother of pearl or the real thing. These earrings were purchased at an estate, along with other pieces we will be listing, and were framed and mounted on black velvet with lace. The framed collection included other vintage jewelry marked "Japan" and "Czechoslovakia", and one piece that tested positive for Bakelite. Please save our store and watch for other items from this collection. See photos.
