I believe 10K FG means 10 Caret Fine Gold.

A lot of ppl are asking this question - if the G in the FG is kind of angular, it is the Trademark for Fredrick Goldman, the manufacturer of the ring.

I found the answer to what the "325" means... It is valuable according to this information: What does the stamp 325 mean on jewelry? Answer That indicates the purity of the metal. Coins and gold bars are usually 999,9 out of 1000. In this case, the item contains 325 out of 1000 parts of pure (gold). In jewelry, the rest is usually filled with fine gold and gold mixed with other fine metals. Sterling silver has a purity of 975 out of 1000.

FG are the initials of Frank Gasparro, who designed the Lincoln Memorial reverse.
FG stands for the designer of this coin, Frank Gasparro.
If the "A" is set at an angle, it is more likely not an A after all, but a G. Fredrick Goldman is a ring manufacturer that uses the "FG" jewelers mark. The F is vertical and the G is slanted or stylized.
The 14K P means "Karat Plumb" which is solid 14K gold. The "FG" stands for Frederick Goldman, who founded Frederick Goldman Inc. in 1948 in New York City. Frederlck Goldman has been creating amazing bridal rings since 1948. The newer rings have a copyright stamp next to the "FG". And NO, the FG never stands for filled gold.
