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.
Look inside the band of the ring. It should be stamped 10K, 14K, GF10K, GF14K, SS/GF. The 10 and 14K means it is gold. The GF means it is gold filled and not gold. SS means it is sterling with a layer of gold bonded over it.
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!
Filled or "Gold Filled" Sometimes it will say GF
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
The 10K GF stands for 10 Karat Gold Filled, while the v20 maybe a manufacturers stamp.
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.
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.
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.
in all probably hct is a company ident .mark if hge (heavy gold electroplate) ge (gold electroplate) gf (gold filled) P (means plum gold or exactly 18k,14k,12k,10k,9k,)
The P means Plumb, which indicates true carat. If the item says GP it indicates Gold Plated or GF means Gold Filled.
that means gold filled not real gold.
Are you looking at it or buying/selling it? 10-kt gf looks the same as 10-kt solid gold. But that's where the similarity ends. 10 karat filled gold is a very thin layer of 10-kt gold bonded to each side of a thicker sheet of a base metal.
Gd on gold usally means gold dipped (Gold Plated), GF = Gold Filled
In the U.S., solid gold jewelry is marked with the purity and the hallmark (trademark) of the maker. So, for example, my wedding ring is marked "14K FG" which means it is 14 karat gold, made by Frederick Goldman, Inc. The maker's hallmark can usually be found by searching the US Patent and Trademark Office's trademark database (but the search will probably be tedious).There is, however, an exception, and that is that "GF" is the standard abbreviation for "gold filled" which means it is a cheaper metal core coated with gold on the outside. In other words, it is not solid gold. It would be simply crazy for any jewelry maker to select the hallmark "GF" when that normally mean that it is not solid gold, so you can expect that anything marked "14K GF" is not solid gold, although it should also have an indication of the gold content, e.g. "1/20 14K GF" would mean that the gold coating is 14 karat gold, and is 1/20th of the total weight.
gold filled unlike g.p which is gold plated GF is full gold and makes the jewelry more valuable
these are the proper hallmarks 24 Karat Gold - 24K or 999 22 Karat Gold - 22K or 917 21 Karat Gold - 21K or 875 18 Karat Gold - 18K or 750 14 Karat Gold - 14K or 585 10 Karat Gold - 10K or 417 9 Karat Gold - 9K or 375 14 Karat Gold filled - 14K GF or 14K/20 Sterling Silver - 925 Pure Silver - 999 the ratio is A/24=B for example 10/24=0.417 therefor 10K=417
GF stands for "Gold Fermented" or plated, so 18K GF means 18 Karat Gold Plated.
AMCO is the company that manufactured the piece of jewelry. The 14K represents the carat weight of the gold. The GF stands for gold filled. AMCO went out of business in 1970.
Ok What I think that it means is 14KT = 14karat GF=gold filled and ESPO is the maker. Sometimes when marking the piece the letters don't always line up exactly the way that they should. This is my best guess.
The GF stands for gold-filled, I believe the H stands for hard.The item is gold-filled, meaning it has a micro-thin layer of 18K gold over a base metal.Older gold-filled items such as pocket watches used to be stamped 1/20 12K GF, meaning 12 Kt gold (50% pure) is layered over the base metal, with the gold weight being at least 1/20th of the total weight of the item.
it means gold filled. a layer of real 9ct gold on top of a cheap metal ie copper
The letters GF indicate an item that is not solid 18K gold, but is gold filled. That means that the inner metal is something other than gold, and there is a layer of gold on top. Heavier than electroplate, but much lower value than solid gold. By law 1/20th of the weight will be gold of the purity stated- so 19/20ths is something else- usually brass.
