I have an 18kt gold chain.The thing that worries me is one of the marks on it is PK.has anyone seen this and know what it means.Thankyou for any advice.
GIB hit the nail on the head. plumb gold means karat marked is the exact weight...... PLUMB GOLD means the piece contains the precise amount of gold in the alloy that the Karat mark indicates. It use to be 14 kt could actually be 13.5 Kt and still be marked 14Kt.
