HALLMARKING
Government hallmarking is used by several countries to protect the public from fraud and traders from unfair competition. Introduced in 1327, British hallmarking represents one of the earliest forms of consumer protection.
The British hallmark consists of three compulsory marks:
- The sponsor or makers mark (i.e. the entity who presented the jewellery to be hallmarked by a British Assay office).
- The guaranteed standard of purity of the precious metal in parts per thousand.
- The Assay office that tested and marked the jewellery.
It is a British legal requirement to hallmark all jewellery containing over 1 gram of gold and over 7.78 grams of silver. Naturally, all GemsTV jewellery fully complies with the British Hallmarking Law.
Another way GemsTV makes your jewellery special is by voluntarily adding a date symbol (i.e. the year your jewellery was hallmarked). While no longer a legal requirement, imagine the feeling your great grandchildren will have when looking at the hallmark and being able to use the Internet to identify the year the jewellery was made.
Sponsor mark
This shows the entity responsible for sending the jewellery to the Assay Office. The sponsor may be the manufacturer, retailer, importer, etc. In our case, the mark “GTV” or “DK” proves that your jewellery is genuinely from GemsTV.
Standard marks
These show the standard of fineness (i.e. the purity of the precious metal in parts per thousand).
Assay office mark
There are four British Assay offices that hallmark jewellery - Birmingham (Anchor), Edinburgh (Castle), London (Leopard’s Head) and Sheffield (Rose).
