Once a jewellery collection has been created, it must be sent for testing. All Azendi jewellery is sent to the Edinburgh Assay Office. A tiny sample of every single piece of jewellery is tested using x-ray technology and laser analysis. Modern techniques mean that you cannot tell where sampling has taken place on your jewellery. During the assaying process, the Assay Office will test the metal to find out how fine it is. Is it sterling silver, is it 9ct gold? After testing, if the jewellery meets the legal standard of purity requirements, each piece is stamped with a hallmark. Laser marking is now commonly used to apply a hallmark, although many objects are still stamped by hand.
Hallmarks answer three important questions; who, what and where? A hallmark stamp consists of at least three compulsory marks which tell you the answers to these questions. These are the Sponsor’s Mark, the Fineness Mark and the Office Mark. The Sponsor’s Mark shows who has sent the jewellery for hallmarking and consists of initials within a shape. In the case of Azendi, our sponsor’s mark are the initials ‘A' and 'Z’ within squares. Each Sponsor's mark is unique and registered at the Assay Offices.
The Fineness Mark shows the precious metal and the level of purity. All sterling silver jewellery would have a ‘925’ hallmark applied. 9ct gold jewellery will have a ‘375’ mark applied.
The Office Mark shows where the jewellery was tested; the symbol for London is a leopard head, for Birmingham an anchor, for Sheffield a rose, and for Edinburgh, a castle. All Azendi jewellery is hallmarked at Edinburgh Assay Office so bears the castle mark next to our Sponsor's Mark and the Fineness Mark.
Additional marks may be applied to jewellery, such as a date stamp, but any item sent for testing will show at least the main three stamps.
There are a couple of exemptions to the hallmarking rules; any sterling silver items that weigh less than 7.78 grams do not need to be hallmarked, and any gold items that weight less than 1 gram do not need to be hallmarked.
If you're unsure of what your jewellery is made of you can use a magnifying glass to look on your items and find out. On rings and bangles you will usually find the hallmark on the inside curve. On necklaces, bracelets and chains the hallmark is usually near the clasp - either on the clasp or on the main loop joining the clasp to the chain. On earrings, the hallmark would normally be on the earring post.
