Assays & Hallmarks

What we do.

The Assay Office assays and hallmarks (tests and certifies) items of gold, silver and platinum jewellery and or plate manufactured in Ireland or imported. In Ireland all items of gold, silver and platinum are subject to compulsory assay and hallmarking. All standards of fineness are minimum standards with no minus tolerance and there are no exemptions by weight.

The Company Of

Goldsmiths of Dublin.

The Company of Goldsmiths of Dublin governs the Assay Office which is situated in Dublin Castle. The Company was established and incorporated by royal charter of Charles I on 22nd December 1637. The craft of goldsmith existed in Ireland long before this, during the prehistoric times as early as 1800 BC.

It flourished also following the introduction of Christianity in the fifth century and during the medieval period following the Anglo-Norman invasion in 1169. There is mention occasionally of the existence of a guild of goldsmiths in Dublin during the sixteenth century.
