This is a vintage painting that I've turned into a pendant necklace. This image was a painting by John William Waterhouse entitled A Mermaid.
The necklace and frame that this picture is in is of my design and manufactured for me. You cannot get it anywhere else and I do not sell them separately. It measures from the outside edges, 1in. x 1-11/16in. or 32mm x 40mm. It comes in either an antiqued silver-plate or antiqued gold-plate. In a larger format it allows the art to be better seen. It does open up and a new picture can be slid into the frame. The chain necklace measures 18 inches long.
