Single Loop Continuing Gold Toned Chain

Necklace is %100 costume jewelry, gold tone, with a single link chain which does NOT open, this is a continuing chain. I doubt one would be able to wrap this twice over the neck, as this is displayed. I've wrapped it like this for picture purpose only. Please see pictures for measurements I don't know much else about this necklace other than it was purchased by my grandma and found prior to her estate sale. Questions? Please ask prior to purchase.
