How to Verify the Purity of Gold Bars
Buyers must ensure that a gold bar meets the correct purity standards. Verifying authenticity can prevent fraud and ensure long-term value.
Ways to check gold bar purity:
- Hallmarks and branding – Reputable gold bars display the refinery's stamp, weight, and purity.
- Acid test – A small scratch test with nitric acid can confirm gold content.
- Electronic gold testers – These devices measure conductivity to determine purity.
- X-ray fluorescence (XRF) analysis – A non-destructive test professionals use to verify metal composition.
- Magnet test – Since gold is non-magnetic, real gold bars should not be attracted to a magnet.
Buyers looking to purchase from a gold bar dealer Philadelphia should always verify authenticity before buying. Secure transactions and proper testing help protect investments.
