Gold has been a precious metal for thousands of years, valued for its beauty and scarcity. When buying or trading gold, it is essential to know its quality. The fineness of gold is assessed in karat weight, with pure gold being twenty-four karats. However, most gold jewelry and items are not made of solid gold; they are often mixed with other metals to improve durability and reduce costs. Grasping how to assess the purity of gold can help individuals make knowledgeable decisions when acquiring or disposing of this precious metal.

This technique is often used by professionals in the jewelry industry due to its accuracy and ability to test without damaging the item. While XRF testing may be more costly than alternative methods, it is extremely reliable for determining gold purity.
