Before You Test: Confirm the Item and Paper Trail
Start by identifying exactly what you have, including whether it’s jewelry, bars, coins, or scrap. Note the maker’s mark, serial numbers, hallmark stamps, and any authenticity documents that came with the piece. Ask the testing provider what techniques they use and whether they calibrate equipment before running samples.
A strong process often includes both non-destructive screening and a controlled verification method for final reporting. For example, an initial screening may indicate likely karat range, followed by more definitive testing to confirm exact composition. Ensure the provider can explain uncertainty levels, sample handling, and how results are documented. If you’re buying, insist on a written report; if you’re selling, use the report to support your asking price with evidence.
Verification Day Checklist: Sample Handling, Standards, and Chain of Custody
When you bring an item for assessment, establish a chain of custody before any testing begins. Confirm the item ID, the declared weight, and the condition at the time of submission, and have the tester record these details. Request that the sample handling steps are described, including how the item is prepared and how any measurements are taken. This protects both parties and helps prevent disputes caused by missing context or incomplete documentation.
Ask the provider to use reference standards during testing, such as certified calibration materials that match the claimed metal type. Confirm that calibration records are available and that the equipment is verified according to internal quality procedures. For transparency, request details on how the test environment is controlled, since results can vary if conditions are not consistent. If the item is small or irregular in shape, ask how they ensure representative sampling and avoid misleading readings.
