14KCG jewelry stamp meaning.

I have a silver color ring that I found while metal detecting and it's marked 14KCG. Is it white gold? Is CG the maker and who and where is it from?

I will say this is an odd marking for me to see on a ring. This marking is most commonly found on alloy pendants that have a light gold plating.

It is entirely possible that this is white gold and CG is a maker's mark but my first response is this is a light gold metal alloy.

Hello I have a necklace that says 18c on one side and 926 Italy on the other side it's a 20 inch necklace that appears to be silver could be white gold I can't find information anywhere please help thank you

This one is a little confusing as 18c almost certainly means 18 karat gold while the 926 stamp is for 22 karat gold. It could be that some links are 18 karat and others are 22karat. I will also say that most necklaces are not made of 22k due to how soft the gold will be with that much purity.
