"XP" is a symbol engraved onto jewelry; it is the name of the manufacturer (in China) which is known for producing jewelry from various metals including SS, GF, etc. Unfortunately, the manufacturer rarely indicates which metal is used. So, if you are buying on ebay, and the auction states gold filled by XP, and it's got a Buy It Now for 99 cents, it probably isn't manufactured from the 14k 1/20 GF that Americans are accustomed to buying. (I just inquired about this from a Chinese merchant who explained this to me.)
I have a necklace with a brass hang tag/dangle of a brass hear with the initials SR on one side and USA on the other. Any ideas.
