The easiest and best way to figure out if your jewellery is gold is to
get it assessed by your local jeweller. They’ll look for your jewellery's hallmark to confirm that
it's gold. Some jewellery even has visible hallmarks that you can see with the naked eye. If you can
read yours, simply enter its details when filling out the online form.
The marking will either be an obscure 3-digit numeric set, such as 585, or it could be an obvious
tell such as 14k for 14 karat. The 3-digit reference ties in with a common standards chart where
number sets dictate the percentage of gold involved.
999, for example, is the purist amount, essentially 24 karat gold with a 99.9999% purity. On the
other hand, 750 is indicative of a 75% purity level, better known to most as 18 karat gold. The
3-digit stamp sequence generally gets identified as follows:
- 999.9 or 999 - 24 karat gold
- 916, 917 - 22 karat gold
- 750 - 18 karats
- 585, 583, 575 - 14 karats
- 417 - 10 karat gold (typically the lowest one you will find in U.S. markets)
- 375 - 9 karats
