The term 14KP stands for "karat plumb" gold---meaning exactly 14K....no more, no less. KP does NOT, I repeat does NOT mean plated. It is solid 14K gold.  Karat weights are usually determined with a small, fractional variance allowed by law. Karat gold which has NO fractional variance at all is called "plumb" gold -- typically identified with a "KP" hallmark.    Thinking KP means gold plate is a common mis-conception but if you will please  Google " 14KP "  you'll get the entire explanation of the origin for this term.  Check it out!  Carol
