NF 925 Ring: Understanding Sterling Silver & Diamond Authenticity

The "NF 925" stamp on a ring tells you about the metal, but not about the diamonds. Here's what it means:

* 925: This means the ring is made of sterling silver, which is 92.5% pure silver.

* NF: This is the maker's mark or brand. The specific meaning depends on the manufacturer.

Whether the diamonds are real or not has nothing to do with the stamp on the ring. To find out if they are real or not, you could take the ring to a professional jeweller who would be able to help.
