What does 925 mean on jewelry?
A 925 stamp states a fineness of 925 parts silver per thousand, commonly described as sterling silver. The FTC also advises that U.S. silver items carry the name or registered trademark of the business responsible for the mark. A 925 stamp does not by itself authenticate a piece of jewelry.
Is 925 real silver?
925 is the standard fineness statement for 92.5% silver, but a photograph cannot verify that the metal meets the stamp. Testing is separate from reading.
Where should a 925 mark be photographed?
Photograph the entire object first, then the complete mark group, then a sharp close-up from a second light angle. Record dimensions separately. Preserve the original file; do not polish, scrape or retouch a mark to make it easier to read.

| Evidence | What it states | What remains open |
| 925 stamp | Claim of 925/1000 silver fineness | Whether this object tests accordingly |
| Name or trademark | Party standing behind a U.S. mark | Workshop date and authenticity |
| Receipt or test | Transaction or measured result | Historical attribution |
Does 925 show where jewelry was made?
No. The number states fineness, not country, maker or production date. Other marks and records may address those questions.
What can 925 prove?
A photographed mark is evidence to research, not a certificate. A mark alone cannot prove authenticity, exact age, maker attribution, precious-metal content, condition or market value. Compare the complete object with documented records and obtain an in-person test when the decision depends on material or authenticity.
What should a buyer ask?
Ask for the total weight, dimensions, seller return policy, clear photographs of every stamp and any independent metal-testing record.
