ACO is hallmarked on a necklace I own, what does it stand for?

1. knocked off tat.
2. the makers initials, sounds like you have some fakery.
3. take it to a JEWELER
4. I think it may be American Chain Company. I had one marked AC., and it was that company. But they used several different marks.
5. all crap origins!
