I have a beautiful necklace w/ 4 green pearls, abalone shell beads and silver tone swirls. The swirls and chain don’t stick to a magnet and I thought they are sterling silver but I can’t find any markings on the them showing that they are. It has a nice strong magnetic clasp. It is just over 15 inches long. The matching earrings have green pearls and silver tone but they do stick to a magnet so they aren’t sterling silver.
