Jewelers test gold using methods like the acid test, where they apply nitric acid to determine gold purity based on the reaction. Another method is the magnet test; genuine gold is non-magnetic. They may also use electronic testing devices for precise measurements. For high-value items, a X-ray fluorescence (XRF) analyzer can precisely determine the gold content. Ensuring authenticity and quality helps maintain trust and value in gold transactions.
