How is gold checked? A complete and easy guide

1) X-Ray Fluorescence (XRF) machine

This machine indicates the purity of the top layer of gold without cutting. It is used to check common jewelry and gold bars, but it does not always detect internal alloys.

2) Ultrasonic Testing Machine (Ultrasonic Tester)

This machine sends sound waves into the gold to check its internal structure. If there is tungsten or any other metal inside, the difference becomes apparent immediately.

3) Electric Conductivity Tester

Gold has a special ability to conduct electricity. This machine indicates whether the gold is pure or alloyed based on the flow of current.

4) Cut Test

In this method, a small piece of gold is cut to look inside. If there is any other metal inside, it is detected immediately, but the jewelry gets damaged.

5) Fire Assay Test

This is a laboratory test in which gold is melted to extract its original purity. It is the most accurate but also the most expensive and time-consuming method.

Result:

Whether gold shines or not,

fraud always shows shine.

Make purchases wisely.
