Use this hardened steel quality stamp to mark your fine silver silver pieces as 999 (pure fine silver). Place against the silver and strike gently with a hammer. Bent shank to make it easy to stamp rings. Each letter is about 0.8mm high and the stamped mark is about 1.6mm wide. Often called a hallmark stamp. Excellent for smaller pieces, or pieces you give away, which don't have to be hallmarked.

Please note that according to UK law, this is not the same as hallmarking your piece, you're simply marking it with the quality. Hallmarking can only be done through a UK Assay office.
