How to read it
The FTC’s jewelry guides allow a gold alloy to be marked with its karat figure, with or without the word gold: 14 Karat, 14Kt. and 14 K. are among their own examples. The UK’s Hallmarking Act says 14 carats indicates gold of 585 parts per thousand, and 585 is the figure its hallmark strikes for that standard, which is why the same gold can be stamped 14K in one country and 585 in another.
Also searched as: 14K, 14 karat, 14KT, 585.
A stamp is a claim about the metal, made by whoever struck it. This page says what each mark means under the rules that define it; it doesn’t test or value anything.
