the GF stands for GOLD FILLED
Very little. 10k stands for 10 karat, and GF means gold-filled. The ring is not solid gold and is mostly base metal.
G.F. Espo is the manufacturer of the ring.
gold filled
good chance it means 10k gold filled but you can always take it to a pawn or jewelry store to have it gold tested. I am a gold buyer and the above answer is half correct. The part where you should take it to a gold buyer and have it tested is correct. The part where they think it is filled may not be correct. I have here a ring I just purchased that says "10k F" I have tested the ring and it is pure 10k gold. No filled or plating. I attribute this to the makers mark and there is a symbol after the f. Also when gold if filled the marking would more than likely be GF and not F. Hope this helps!
The 10K GF stands for 10 Karat Gold Filled, while the v20 maybe a manufacturers stamp.
GF= stands for "gold filled" Gold Filled (heavy plating), usually has a fraction, For Example:1/20 10K GF found at: http://nitacreations.blogspot.com/2007/10/jewelry-markings-what-do-they-all-mean.html
If your ring has 14k, 10k, or 18k with the initials it is gold. GF with a number like 14k is gold filled and not worth as much. No value given in gold or silver it is costume.

Hi... when you see P 10k or 10k P on a piece of jewelry, it means that the purity of the gold is guaranteed to be 10k or better. The "P" means PLUMB it is a higher purity of gold making it a better quality. "P" does not mean any kind of plating. Gold plating marks are as follows: GP, RGP, HGE, GF.
