Looking for information on 18K CS marked jewelry

[MRBeyer]

A ring I bought at a thrift shop says 18K CS, I can find mention of Tiffanys selling 18K CS rings but can't seem to find anything else about the marking. The stones are CZ, wondering if the the CS means coated silver or Cubic Stone.

Could that be GS for Gold Shell?

Are you sure it is marked CS instead of CZ? Breezie

The initials after the 18k ect mark are 99% of the time a designer makers mark.

Try looking at it flipped over the other way! Could it possibly say SJ many people confuse this mark for CS but it stands for saint john

Thank you for the insight. Until I know for sure I am thinking it is the makers mark. It is oriented the same as the 18k mark so I read it as CS.
