Short answer: “925” means the item is represented as sterling silver: 925 parts out of 1,000, or 92.5%, are pure silver. The remaining alloy helps make jewelry practical. A stamp is useful evidence, not an independent laboratory guarantee.
Common Silver Marks
| Mark | Meaning |
|---|---|
| 925 | 92.5% pure silver |
| Sterling / Ster. | Sterling silver |
| 999 | Fine silver |
| Silver plate | Silver layer over base metal |
The FTC states that silver, sterling, and sterling silver describe products containing 92.5% pure silver and that pieces are sometimes marked 925. It also advises looking for the responsible company’s name or trademark.
Where Is the Stamp?
Check the pendant back, bail, clasp, or a tag near the clasp. Because pendant and chain may be sourced separately, inspect both.
Does 925 Tarnish?
Yes. Tarnish is a surface reaction and does not by itself mean the item is fake. Humidity, cosmetics, perspiration, sulfur, storage, and alloy composition affect darkening. Use our cross necklace cleaning guide.
How to Inspect a 925 Cross
- Use a loupe for the 925 and maker’s marks.
- Compare stamps with the product description.
- Check the seller and return policy.
- Do not rely on a magnet test alone.
- For valuable pieces, request professional testing.
