Every Chupi piece is hallmarked in the Assay Office in Dublin Castle. It is our guarantee that your piece is made using the highest quality metals, with love here in Ireland.
The Assay Offices are a network all around the world that ensure all precious jewellery is hallmarked appropriately. The Assay Office, from reading a piece’s hallmarks, will be able to tell you who made your piece, what it is made from, and where your piece was made. In a hundred years when your piece is an heirloom the story of your piece will always be there, engraved like a fingerprint.
WHAT IS A HALLMARK?
Precious metals are hallmarked to let you know:
- Maker’s Mark: Who made your piece
- Purity Mark: What precious metal your piece is made from
- the Assay Office at which your piece was hallmarked
THE MAKER’S MARK
Each maker is allowed three letters as their unique maker’s mark so we have shortened Chupi to CHI
THE PURITY MARK
This shows the purity of the precious metal content. The fineness is indicated by a millesimal number (parts per thousand) and the precious metal is indicated by the shape of the surround.
14kt Gold = 585
Silver = 925
THE ASSAY OFFICE MARK
This symbol shows which Assay Office tested and marked the item. Every Assay Office in the world has its own mark. The Hibernia mark is the symbol of Dublin Assay Office and shows a seated lady.
