The gf most probably indicates gold filled, which means the piece is not solid gold.
The gf definitely stands for gold filled (it has also been known as rolled gold. Thin sheets of real 18-kt gold are roll-bonded to both sides of a thicker sheet of base metal. This process gives the item (pen, watch, jewelry, etc.) a more durable coating of gold than if it were gold electro-plated (gp).
Well, 18k alloys soft yellow gold ring it's not authentic ; because it is mixed alloys and it's not original from the nature.
GF stands for "Gold Fermented" or plated, so 18K GF means 18 Karat Gold Plated.
Typically, real gold will be stamped with values such as 14k (14 karat), 18k GF (18k gold-filled), etc. The best way to tell; however, is to take the piece to a jeweler who has a gold testing kit or gold testing acids.
Real gold will have a stamp on it telling what it is. It should say 10K, 14K, 18K, 24K, or gold filled. Gold filled (GF) is not real gold. If the chain or pendant or ring doesn't have this on it then it isn't real gold.
This means that it is not pure gold, The 18 k gf tells you that this is a gold filled piece of jewelry, which means it is covered with a layer of gold but has a base metal underneath this layer.
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.
