Jewelers often stamp gold pieces with their carat rating, making it easier for buyers to recognize the purity.

XRF testing can provide exact measurements of the gold amount and identify other metals present in the mixture. This technique is often used by experts in the precious metals industry due to its accuracy and ability to test without damaging the piece. While XRF testing may be more costly than alternative methods, it is extremely reliable for determining gold quality.

In conclusion, correctly evaluating the purity of gold is essential for anyone involved in acquiring or trading this valuable metal. Grasping the carat system, using acid testing, and considering sophisticated methods like XRF testing can help individuals make informed choices.
