What is this line?

I’m a be to this group.... I purchased this set of jewelry at estate sale. I don’t know what is this line stands for.... As I understand 12K is 50% gold, and stone turquoise... May be I’m mistaken. How much is it cost approximately? Just it is interesting Thank you

The GF I believe stands for gold filled, meaning it is not solid gold. It is silver or another metal plated with gold.

i think it stands for 20% 12k gold filled

it won't tarnish like gold plated jewelry but like lydial said it's not solid gold

12kt gold filled. Different than just plain 12kt. It's gold over pot metal or maybe silver. There's more gold than just gold plating I think.
