This necklace was handmade by me with a gorgeous antiqued brass metal mermaid pendant. This stunning mermaid features water and lily flowers, all swirling around in such a romantic style! the back is hollow as shown in the pictures. The pendant measures 2 inches long by 1 1/2 inch wide. I have added a brass cable chain along with a lobster clasp and 2 inch extender. Total adjustable length is 17 1/2 to 19 1/2 inches. Thank you -
