Bullion Testing

We provide comprehensive testing services for gold and silver bullion — including bars, coins, biscuits, and doré. Our laboratory is equipped to handle individual pieces as well as bulk lots. For investment-grade bullion, we provide assay certificates that detail the methodology used, the measured purity, and all relevant identification information.
