Vintage Sterling 1.S ITALY 24" 1mm Herringbone Necklace with 6 spaced Silver Beads.  Herringbone is approx 1mm wide. Clasp is a vintage push type locking clasp and I think a lobster clasp might have been added to it at a later date to make it easier to put on and remove. Lobster clasp has no markings on it at all. Might not be silver. Push clasp is stamped with what looks like "1.S.ITALY" and above that is stamped 4 letters and "925" The letters might say "BRVB" or "8RVB" or something like that - Very hard to make out without proper magnification. Pre-owned in Good Condition. Unpolished and will come with original estate patina. No dents or bends in chain that I can detect. Untested.
