Letter Markings On Gold Jewelry. More commonly, this marking is used for watches. You'll notice that your gold jewelry is stamped with a two-digit number followed by the letter "K" or sometimes a three-digit number indicative of the percentage of gold in the item.
These letters and numbers indicate an item's purity. Most gold will be marked with mysterious combinations of numbers and letters. Gold-Traders has compiled a gold hallmark identification wizard to help decipher the markings that are stamped on your item.

This marking indicates the name of the manufacturer, where the product was tested, the degree of purity of the jewelry material, when the product was produced, and whether it was produced for a specific purpose. Works primarily in gold and platinum. In addition to Maker's Marks, some countries require hallmarks, which are given by the country where manufacturing took place.
