I have a thick silver tone rope chain necklace with a lobster claw clasp. It is in great condition and pretty sparkly. It is 24 inches long and 35.88 grams. I don’t see any maker’s mark or metal content markings so I don’t know what the metal actually is but it sticks to a magnet so it’s not sterling silver.
