I have a vintage sterling silver box chain necklace with an oval pendant with a large pearl. The necklace is 18 inches long and marked 925 Italy. The pendant is an oval that is just over 1 inch tall with a large real pearl. The metal on the pendant isn’t stamped and looks like it is silver plated copper or brass. Some of the silver has rubbed off and there is some gold color showing through. That’s why I listed it as fair condition. A magnet doesn’t stick to it.
