Purchased two chains with same/similar mark, what is it?

[RetroQT]

I purchased two chains (separate times from different vendors) and both have the same/similar mark. Do you know what it means?

I’m curious because I bought these chains years apart, one from a store that sells estate pieces and then the other from an individual. Thought it interesting that they both had that mark. Wasn’t sure if it was a makers mark or if it was something standard pertaining to the gold. I hadn’t much paid attention to this before PS.
