14k GF PJ STG PJ ON A BRACELET Hi! I have this GREAT site that I have kept on my favorites list forever. It will tell you all about markings on jewelry from A to Z. It's been a great help to me so try the link below. You can click on it or if that doesn't work, cut and paste into your browser! I hope this helps! Have fun :o) The link actually brings you to the "R" page, but you can find "F" at the top, underlined and you can go from there. It's really interesting! Also, 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.
STG should mean Sterling (Silver).
It is a stamp from Ghana - the former Gold Coast
it would stamp gold with 2,000,234,567,890,122,3,,4,,5,5,6,6,7,7,8,,0,0 which means $52
Not a thing. StG was just a more literal name for the MP44 (the StG prefix stands for Sturmgewehr, and MP stands for maschinenpistole).
Gold electroplate. Not gold.
