Why Certifications Matter in Precious Metal Testing
Certifications create a foundation for accuracy in precious metal evaluations. They define how purity and weight should be measured and provide guidelines for interpreting results.
Certified evaluators follow standardized methods, which means two different tests produce the same outcome. That consistency allows sellers to trust the results and make informed choices.
Unverified testing often comes with risk. A pawn shop or casual buyer may rely on visual inspection or outdated tools. Those methods leave room for errors and guesswork, which can cost sellers money. Certified assessments, on the other hand, remove doubt and provide reliable information.
A certified test turns opinion into fact.
Common Standards Used in Metal Assessment
Metal assessment follows established standards that keep testing accurate and consistent across the industry.
In the United States and worldwide, certifications guide how gold, silver, and platinum are measured. Gold is evaluated in karats, ranging from 10k to 24k, while silver and platinum are tested by percentage purity.
Hallmark stamps on jewelry also act as industry-recognized identifiers of quality.
Organizations such as ASTM (American Society for Testing and Materials) and ISO provide protocols that define testing procedures. Their guidelines cover the equipment used, how results are recorded, and how purity levels are confirmed.
Advanced methods like XRF X-ray testing meet these standards by delivering precise measurements in real time.
Key standards include:
-
Karat grading for gold (10k, 14k, 18k, 24k)
-
Purity measurements in percentages for silver and platinum
-
XRF X-ray testing protocols
-
Industry-recognized hallmark stamps
-
Compliance with ASTM and ISO guidelines
Standards create consistency in a market that depends on trust.
