I have a sea glass pendant with a silver swirl and wrapped loop on a silver tone box chain necklace. It is a seafoam green color (the first and last picture is most true to the real color). It’s 1 1/4 inches tall. I can’t find a metal content marking but a magnet does not stick to it. All of the ones I’ve found that are similar say sterling silver. The chain is 16 inches long. It is marked 925 Italy but a magnet sticks to it so I don’t know what the metal actually is and am pricing it like it’s not sterling. See my other ads for jewelry, artwork, home decor and more.
