- Electrical resistivity works mainly on gold and platinum, not silver. Acid tests determine the karat value of gold coins but also damage the coin. Neither method can be used for detecting gold plating. X-ray fluorescence (XRF) analyzers provide a fast, accurate, nondestructive alternative for assessing coins.

Sep 25, 2024 · Here are some different ways to test for pure gold, as well as each of their pros and cons. 1. X-Ray Fluorescence (XRF) X-Ray Fluorescence (XRF) is a technique for determining the elemental makeup of materials. To test for gold, a device called an XRF analyzer or XRF gun is aimed at the material and exposes it to high-energy X-rays.
Feb 13, 2023 · PCGS experts use a variety of technical methods when identifying and authenticating coins. One essential and often revealing examination is X-ray fluorescence spectroscopy (“XRF”), a form of non-destructive elemental analysis providing information about the metallic composition of a coin’s surface.
Sep 25, 2024 · Whether you’re a jeweler, a pawnshop owner, or in the precious metals industry, accurately determining the gold content of an item is crucial. After reviewing various methods, you’ve narrowed your choice to XRF analyzers—the industry standard for non-destructive, quick, and precise testing.
Dec 8, 2020 · X-ray fluorescence spectroscopy (XRF) is a non-destructive analytical technique used to determine the elemental composition of materials. Handheld XRF analyzers work by measuring the fluorescent (or secondary) X-rays emitted from a sample when excited by a primary X-ray source.

- How Does An Assayer Or Jeweler Verify My Gold’s Authenticity?
Have you ever purchased a gold bar from a private seller and questioned its authenticity? There are several ways to test your gold products, but the most accurate and trusted methods involve employing a local jeweler or assayer or a very expensive non-invasive machine using high-technology means.
Use the following recommendations as a starting point to get a feel of whether your gold products are authentic. If they do not pass these simple tests, it is worth the time and effort to have a professional test them. It is advisable to employ more than one test. 1. Look at the color. Gold has a distinctive, warm yellow color. Its brightness can v...
If the above tests are inconclusive, you can try three more tests at home, but some are more involved and complicated than others. None of these tests are foolproof, either. Counterfeiters will always try to stay one step ahead, which means their methods have and will become increasingly closer to genuine examples. If you are unsatisfied with the r...
If the idea of conducting science experiments at home does not sound like your ideal Saturday night, take your gold to an assayer or jeweler. Assayers and jewelers will have one of two sophisticated machines to help authenticate your gold, whether it is jewelry, a bar, a round, or a coin.
