Many people, after seeing a number engraved on their jewelry, don't quite understand what it means and ask us. Today we're going to talk about the meaning of numbers on jewelry.
Gold jewelry numbers
The numbering found on a gold jewel indicates its alloy, that is, the amount of pure gold it contains. These are the most common numbers you might find:
916
If we find a piece that has this number engraved on it, we will be looking at a jewel that contains 91.6% pure gold, while the rest (8.4%) will be made of other materials (usually silver and copper).
750
When a gold jewel has this number engraved on it, it indicates that its gold purity is 75% and that the rest of the jewel is made with other metals, such as copper or silver.
585, 375,…
Whatever number we find on the gold jewelry will indicate its level of pure gold versus another percentage that will contain other metals.

Silver jewelry numbers
It's also possible to find this numbering engraved on your silver jewelry. We need to understand what it means, exactly the same as with gold: the alloy, or in other words, the percentage of pure silver used to make the piece. The most common numbering found on silver jewelry is:
925
This number indicates that the silver piece is 92.5% pure silver, with the remaining 6.5% being other elements. This amount of silver is the most commonly used.
In both cases it is clear that if we find a 1000 engraved on it, our piece will be pure gold or silver.
