The cost of hallmarking depends on several factors. If there are one or two articles, they cost 14 per packet. If there are 3 or more articles, they cost 18 per packet + 1.10 (per article). The cost includes the traditional fineness symbol, sponsor’s mark, date letter, laser application of hallmark and the handling. The cost of hallmarking is usually borne by the jeweller/manufacturer.
The costs will differ on additional services added. Metal bars can also be hallmarked. The Goldsmith’s Company Assay Office releases an updated price list every year.
