I think it's a symbol or mark that showing the standard of an amount of precious metal that used in that jewelry. Every country has their own minimum unit that should be used on a jewelry such as
333 which is 8 carat in Germany
375 which is 9 carat in the UK
417 which is 10 carat in the USA

The "nv g" stamp on the inside of a ring typically indicates that it is not real gold. "nv g" is likely a manufacturer's mark or a stamp indicating that the ring is plated with gold and not made of solid gold. It is important to have the ring tested by a professional to confirm its authenticity.
The "355" stamp inside the gold ring likely refers to the gold's purity, meaning it is 355 parts per 1000 gold (or 35.5% pure gold). The ".925" stamp indicates that the ring is also made with sterling silver, which is 92.5% pure silver.
Not real gold. If there is no 10K stamp or 417 marking, its probably plated. Sorry.

It stands for 14 kt gold and the piece is from Europe usually .That is the national symbol to say it is 14 kt gold .
In a word,no! Hallmarks are a stamp of qulaity only applied to solid gold items.
Gold Plated
KP means gold on vintage pieces. KTP means plated. I’ve never seen KPT before. It might also be the jeweller’s stamp?
GF stands for "Gold Fermented" or plated, so 18K GF means 18 Karat Gold Plated.
