Vintage gold tone link fancy lady necklace

unmarked vintage gold tone costume jewelry necklace! I purchased it at an estate sale a while back. fun piece to wear, it's not too heavy in weight because the back is hollow. no critical signs of wear, besides faint hairline scratches, perhaps. I don't see anywhere that seems like the gold tone has rubbed away or anything like that. looks great! I feel like a fancy lady in it. 😂 measures a little over 17 in long, no maker marks.
