There are a few of problems with magnetic testing, however, which make it an unreliable method. Fake gold chains are not made of solid gold and are often simply gold plated. European gold markings are often expressed in terms of decimals. If you find numbers followed by the letters K, KT, or KP, this is an indication of the karat of the piece, and it is likely that it is made of solid gold.

Similar to gold-plated items, these chains are also made of non-gold metals, but instead of plated with gold, they are wrapped in a thin sheet of it, which is attached to the core metal under high temperature.
