What do the letters NF mean on my jewelry? This is a frequently asked question as there is a huge amount of jewelry with this mark starting from the 1980s. When you see NF stamped on your jewelry it does not mean Nickel Free or Nickel Filled as posted by everyone who is giving out this information as you scroll through the search results. Since sterling silver jewelry does not contain nickel in its alloy there would be no reason to have to identify it as nickel free. The NF mark is not a reference to the alloy contents as it is the registered trademark for the importer. In addition there may be a THAI or THAILAND stamp for the items manufactured in Thailand.
