I didn't know it until I saw the picture! There is no difference between S925 silver and 925 silver. S is the initials of silver, and 925 is one thousandth of the international standard content of silver jewelry.

Just like we buy gold in a gold shop, some are marked with Au990, and some are marked with Au 990, all of which refer to pure gold.

However, the imprint of S925 makes people feel more standardized.

By the way, there are two kinds of 925 silver on the market: natural silver and silver-plated platinum. Platinum-plated silver is not easily oxidized. It is easy to distinguish from each other in luster.
