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.
espo was the company that made it. 925 means sterling silver.
10kt
10 mg gold
Plated with 10kt gold
416 is 10k

When these markings are stamped on a ring 18kt HGT ESPO, HGT stands for heavy gold electroplate meaning the ring is gold with a small amount of 18kt. ESPO is the jewelers stamp, in this case Joseph Esposito of Esposito Jewelry.
