Silver Purity
Testing Laboratory
Employing high-frequency X-Ray Fluorescence (XRF) and traditional Fire Assay techniques to certify the molecular integrity of your silver assets with 99.99% accuracy at Authentic Gem Lab.
Purity Methodologies
Our laboratory utilizes a dual-verification process to ensure commercial and investment grade compliance.
XRF Spectrometry
Non-destructive elemental analysis that identifies the exact composition of silver alloys within seconds. Critical for hallmarking and retail verification.
Fire Assay
The global standard. Using thermal extraction in a cupellation furnace to isolate pure silver from lead and impurities at 980°C.
Hydrostatic Balance
Measuring specific gravity to detect internal tungsten or lead cores hidden inside large silver bullion bars.
Accredited Assays
All results are provided with an encrypted digital certificate valid worldwide, signed by a senior chemical assayer.
Legacy Spot Assay
Acid and chemical streak analysis carefully executed to check antique silverware, heritage coins, and filigree art.
Secure Submission
Each silver item is cataloged into our private ledger with high-resolution macro photography and weight verification.
Multi-Spectrum Scan
Items undergo triplicate scanning using independent spectroscopic sensors to eliminate margin of error.
Certified Assay Report
A comprehensive purity report detailing exact alloy compositions is issued and embossed with our laboratory seal.
