The item is a sterling silver heart locket. The locket measures 20 millimeters long , this includes the length of the bale. The pendant measures 13mm wide. The locket has mother of pearl on the front of it. This will give it a rainbow color effect if you hold it the right way. The back of the locket is plain and engravable. The inside of the locket has a plastic piece for holding in photographs on one side of the locket. The item comes with a 15 inch long sterling silver rope chain. The chain has a lobster claw catch. I will provide a nice pendant box. If buying outside the United States please check with your local post office for customs fees.
