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!
It means it is 10K white gold.
The 10k of 10K THL means the metal is 10 karats. The THL is the trademark of Samuel Aaron, Inc., who is a jewelry designer.
It is depend on the other materials that are mixed into the gold. Every mix has a different dencity. 10K Green Gold 11.03 10K Yellow Gold 11.57 10K White Gold 11.07 10K Red Gold 11.59
In newer designs Ive seen where Ster/10K indicates that the ring is sterling silver, plated with 10K gold. In older designs, the 2 stamps usually mean that part of the ring is sterling and part of the ring is 10K gold.

There is a jewelry maker-Fairy Tale Jewelers-FTJ...10K means almost half the weight of the piece is gold.
10k Edit by Cjulsh 10k is incorrect. 10k jewelry would be stamped 417 which is the amount of gold content. 10k is 41.7% gold. 825 is a lower grade of silver...most silver pieces would have a stamp of 925 which is 92.5% silver. Some pieces will use a lower grade silver 825 or 82.5% silver.

The 2010 Ford F-350-Super-DUTY is 6 ft. 7.9 in. (79.9 in.)10K GVWR Package wide.
A gold ring that is stamped with 10 K F means that the ring is 10 karats. The F means that the ring is considered fine jewelry.
