Understand the hallmark on your jewellery
You’ve found your hallmark
Now it is time to understand what it means. Follow the instructions below for either gold or silver jewellery:
a. For gold pieces, the number stamped on your jewellery will tell you whether it’s either solid gold or gold-plated silver, as well as the karats of the gold. If it has one of the following numbers, it is solid gold:
375 = 9 karat
585 = 14 karat
750 = 18 karat
916 = 22 karat
990/999 = 24 karat
b. If your gold piece has a number that matches one of the silver hallmarks listed in the next section, it means that it is made of gold-plated silver. The piece will therefore be recycled as silver.
c. If your gold piece does not have a hallmark, it is most likely gold-plated brass.
For silver, the numbers are different from gold and if you find one of the following numbers on your piece, it means that it is made of silver:
925 (Sterling Silver)
958 (Brittania Silver)
Cannot identify the number?
With old jewellery pieces, it can be difficult to make out the number. But if your piece of jewellery has a stamp of any kind, however ineligible, it will be made of a precious metal, and we will help figure out which one when you send us your jewellery.
Still not sure?
If you are not sure, please don’t hesitate to contact us or send us your pieces for us to figure it out! We have the expert knowledge needed to identify exactly what metal your pieces are made of.
