Dedicated laboratory for precise determination of gold content and purity.
Our Refining Process
Three mastered stages — from analysis to certification — for uncompromising traceability and purity.
01Assay & Analysis
Fire-assay cupellation and elemental XRF spectrometry establish precise purity before refining.
02Smelt & Refine
Thermal induction smelting and chemical refining bring gold to investment-grade fineness.
03Certify & Vault
Each bar is serial-stamped, hallmarked and secured in an insured, tamper-evident vault.
