XRF testing can provide precise measurements of the gold content and detect additional metals found in the alloy. This method is often used by professionals in the precious metals industry due to its accuracy and ability to test without damaging the piece. While XRF testing may be more costly than other methods, it is highly reliable for determining gold quality.
