S999 mark on a silver bracelet

What Does the S999 Stamp Mean?

The stamp S999 on a bracelet indicates that the piece is made of 99.9% pure silver, also known as fine silver. This is the highest level of silver purity commonly available in jewelry. The “S” stands for silver, while “999” shows that the metal contains almost no alloy content, making it one of the purest forms of silver jewelry.

How Is S999 Different from S925?

Unlike S925 sterling silver, which is 92.5% silver mixed with 7.5% copper or other metals for durability, S999 is nearly pure silver. This makes it softer and more malleable, so while it has excellent purity, it is not as strong as sterling silver. As a result, S999 bracelets are often more delicate and better suited for light wear or collectible purposes.

Conclusion

An S999 mark on a bracelet means it is made of nearly pure silver, offering unmatched purity and shine. While S999 silver is real and highly valuable, it is softer than S925 sterling silver, making it less ideal for everyday use. If you want durability, S925 may be better, but if purity and collectibility matter most, an S999 bracelet is a beautiful choice.
