As UK’s leading manufacturer in gemstone jewellery, we realise the importance of instilling a faith in quality to all our loyal wholesale customers. This promise is not only evident through wearing and admiring our exquisite pieces but is hot stamped into each and every one of our unique designs to give you peace of mind underpinned by a strong sense of authenticity. Each of our creations are hallmarked because the precious metals that we work with are commonly alloyed with other metals. As a legal requirement, our unique Hallmarking not only means that our materials have been independently tested, but it also guarantees that it conforms to all legal standards of fineness and purity. A sponsor mark which may either represent the company or the individual who sends the item for Hallmarking may also be present.

The symbols on a hallmark provide information on the Assay office where the jewellery item was marked and tested, who marked the piece and the year in which this testing and marking was carried out. The standard mark symbol will also be visible which indicates the purity of the precious metal present in parts per 1000.
