I use a hallmark according to the regulations which state that all items over 7.78g must be marked by an assay office.

It’s required that the hallmark is used so that my customers can identify the quality of the jewellery piece they’re buying.


The Full Traditional Hallmark comprises five marks:

  • Sponsor's mark (mine is SFD)

  • Millesimal fineness mark (the 925 is sterling silver)

  • Assay Office mark (the rose is Sheffield)

  • Traditional fineness mark (meets the sterling silver quality)

  • Year Mark (the example here is 2018)
