Learn what a 925 stamp can tell a retailer—and what it cannot prove by itself.
Understand the mark
A 925 marking indicates a claimed silver fineness of 925 parts per thousand. A stamp alone is not independent proof of the entire item’s composition.
Check documentation
Ask for supplier specifications and appropriate test reports when material claims are central to your business. Consider independent testing for higher-risk purchases.
Inspect the complete item
Check closures, posts, soldered joints, and any plated components. Maintain accurate SKU-level records for customer inquiries.
Interpret markings cautiously
A 925 mark generally indicates a claimed sterling silver fineness, but markings vary by manufacturer and jurisdiction. A stamp does not independently establish authenticity, and an unmarked small component is not automatically counterfeit. Read the full product specification and ask what each component contains.
Write accurate product copy
Describe the metal, finish and any plated or non-sterling parts separately. Do not call a whole piece solid sterling if only one component is sterling. Retain supplier documentation and update listings when a design or component specification changes.
Before you commit to an order
Use this short decision record to keep the purchase tied to the specific products and terms you have actually checked.
- Write down the exact product specification relevant to sterling silver jewelry markings and keep the supplier’s written confirmation.
- Calculate the total cost for your actual quantity and US delivery address, not just the advertised unit price.
- Approve a representative sample and agree on how discrepancies, damage and replacements will be handled.
- Retain the quote, order confirmation and sample notes so the next order can be checked against the same standard.
Example: a decision that changes the order
A pendant is stamped 925 while its chain has no stated composition. Describe the pendant and chain separately until the supplier documents both.
Use the example as a question to resolve with the supplier, not as a claim about any particular merchant’s current stock or policies. Save the answer alongside the approved sample and final quote.
Read a mark as a claim, not a test
Common stamps such as 925 and S925 are used to indicate sterling-silver composition. Their presence alone does not verify the entire item, the accuracy of the mark, or the composition of attached components. The absence of a visible mark also does not by itself prove a piece is not sterling silver.
Document the actual item
Record the supplier's SKU, photographs of any marks, component specifications, and invoice wording. Ask whether the mark applies to the full piece or only a part. Avoid repeating vague descriptions such as 'silver tone' as if they were precious-metal claims.
Escalate material uncertainty
For significant purchases or disputed claims, ask a qualified testing service about appropriate methods and their limitations. Some surface-sensitive methods may not establish the composition beneath a coating. Review the current FTC Jewelry Guides before publishing US consumer-facing metal descriptions.
