Examples of British hallmarks for 925 silver. These are displayed in the top of both example characteristics. The bottom instance reveals the additional marks that can additionally be struck, the lion passant, indicating Sterling silver, the date mark (lowercase a for '2000'), and in this example, the 'Millennium mark', which was just available for the years 1999 and also 2000.

Because of this, as well as that off-cuts from sprues are frequently used for assay, several short articles are sent incomplete to the assay office for assay and also hallmarking.
Laser noting additionally implies that ended up write-ups do not require to be re-finished. Laser marking jobs by using high-power lasers to vaporize product from the metal surface area. Two methods exist: 2D and also 3D laser marking. 2D laser marking burns the outline of the trademarks right into the things, while 3D laser noting much better imitates the marks made by punching.
