HALLMARKING

ASSAYING is to determine whether the precious metal content of the alloy in silver or gold meets the required standard. The UK Hallmarking system has been offering protection for over 700 years.

Thomas P Cochran Ltd is registered with the Birmingham Assay Office which has been in existence since 1773.

All of our jewellery is Solid Sterling Silver and is guaranteed nickel free. Each piece in silver of 7.8g or over is sent to the Assay office for hallmarking which is your guarantee of its purity in silver and to meet the legal standard.

Any of our Gold pieces over 1g are sent for hallmarking.
