Purity testing helps estimate how much gold is present in an item. The evaluator should explain the method, its limitations and whether it may affect the jewellery.
Electronic and XRF Testing
Electronic instruments and X-ray fluorescence can provide composition information without relying only on visual markings. Results still need to be interpreted correctly.
Touchstone and Other Methods
Traditional methods may use a touchstone and testing solutions. Some situations require additional verification, especially where plating, solder or mixed components are present.
Ask Before Testing
Confirm whether the method is non-destructive, whether you can observe it and how the result will be used in the final calculation.
Frequently Asked Questions
Is every purity test non-destructive?
No. Confirm the exact method and obtain an explanation before testing.
Can surface plating affect a result?
It can influence some surface-level tests, which may require further verification.
Does one reading determine the final value?
The complete valuation also considers eligible net weight, rate and other components.
