FiorSó is officially registered with the Company of Goldsmiths of Dublin Assay Office (known as the Dublin Assay Office), located in the historic Dublin Castle.
The Dublin Assay Office is the sole Irish hallmarking office in the country and it hallmarks all Irish precious metal jewellery.
It is a legal requirement for jewellery made with these precious metals to be hallmarked, so whenever you buy a piece of jewellery claiming to be made in one or more of these precious metals, make sure to look for the correct jewellery hallmarks.
What does this all mean?
This means that as an Irish jewellery designer and Irish jewellery brand, all FiorSó jewellery made in Gold, Fine Silver (.999), Sterling Silver (.925) and Gold Plated Sterling Silver (vermeil) is officially hallmarked by the Dublin Assay Office.
So you can trust and rest assured that our pieces contain the quality and amount of precious metal you expect.
What Irish hallmarks will you see on FiorSó pieces and what do they mean?
You will see the following hallmarks on our precious metal pieces:

The metal purity mark*:
* Example shown here is for silver. "925" denotes sterling silver (92.5% pure silver), and "999" denotes fine silver (99.9% pure silver).
Why do some FiorSó pieces not include any jewellery hallmarks?
Under Irish law, base metals like brass, gold plated base metals and gold filled items cannot be hallmarked - so you will not find hallmarks on jewellery made using those metals.
