    Found a ring that says 10KP. ?

    Found a womanís ring with very tiny real diamonds and what looks to be sapphires, inside it has 10KP No spaces all the same size. There is also a diamond shape with an M or W in it. Does this mean plated? I donít think I have seen 10 karat plating. Thanks

    I looked it up on line. It stated that 10 karat gold can be as low as 9.5 and that 10KP means it is 10 Karat as stated. I learned something.

    The P stands for "plumb" gold meaning it is exactly 10k - no less. It's a good find .

    What a coincidence! I just found an earring with 10KP stamped on it. I assumed it was plated.

    A large majority of antique jewelry has the KP mark, you might have a nice old ring on your hands

    Here is a cut and paste with additional information yiu might find interesting from a site I frequent
    It sheds deeper detail into the why...

    Karat Plumb - What does it Mean?

    If you've got a piece of gold jewellery you might find a stamp on it that gives the caratage of the piece followed by the letters KP. For example, 14KP, or even 585KP. The KP stands for "Karat Plumb". Obviously the Karat refers to the purity of the gold, while the plumb can be considered to mean 'exact', in the same way that a 'plumb' wall is exactly vertical or a 'plum' surface is exactly horizontal.

    In gold bullion terms it means that the gold stamped with the KP is guaranteed to have a gold purity not less than indicated but could possibly be slightly more pure. So, for example, a bracelet stamped 14KP is guaranteed to contain 58.33% gold or more. Another bracelet stamped 585KP is guaranteed to contain 58.5% pure gold or more. The KP stamp is designed to eliminate the non standard caratage tolerances that some markets allow for. In the USA, for example, gold can be sold at up to 0.5 carat more than it's actual gold content. So, a ring marked 14K can contain just 13.5 carats of gold. Furthermore, even though the USA only allows jewellery to be sold as gold with a minimum of 10 carats purity, the 0.5 carat leeway still applies and 9.5 carat is the actual minimum. So, as a consumer you'd be better off purchasing a ring stamped 10KP than a ring stamped 10K.
