Assay & Verification
Precious metals are valuable because their characteristics can be measured. We establish with buyers what verification a transaction requires before it proceeds.
Verification starts with the metal
Purity, weight and product specifications form an important part of any serious transaction. Depending on the product and the transaction, verification may involve weighing, sampling, assay information, laboratory testing or supporting documentation.
Product purity and specifications are supported by applicable assay and verification documentation provided as part of the transaction and due-diligence process.
We work with buyers to establish the information required for the proposed transaction before proceeding, including the method, who performs it, where it takes place and what result is required.
Verification methods
- Weight & dimensions
- Physical measurement establishes density, which is difficult to reconcile with substituted metals.
- Non-destructive testing
- X-ray fluorescence reads surface composition; ultrasonic testing checks internal consistency.
- Sampling
- For variable material, a representative sample is taken according to an agreed procedure.
- Fire assay
- The long-standing reference method for determining gold content to settlement standard.
- Instrumental analysis
- Laboratory techniques used where high-precision figures are required.
- Documentation review
- Assay information and product records are reviewed alongside physical verification.
Agreement
Method agreed before commitment
Most disputes in precious-metals transactions come from verification arrangements that were never settled in writing. We establish them at the outset: the method, the party performing it, the location, the acceptable result and how any discrepancy is handled.
Buyers may appoint an independent inspector where the parties agree to it as part of the transaction terms.
Frequently Asked Questions
No. Testing arrangements are established according to the requirements of each transaction rather than performed in-house.
