How Acid Tests Work

We use this acid testing method for small pieces or lots of precious metal.

To start, all items are inspected carefully by our highly trained and experienced staff. We then scratch a piece of metal against a basalt stone. This leaves a mark on the stone. By applying certain strengths of nitric acid to this mark and measuring the resulting reaction, we can accurately measure the purity of the precious metal and give you a fair payout right away.

The acid test for gold has been used by jewelers, refiners, and other precious metal professionals for centuries.
