A 925 stamp means the piece is sterling silver: 92.5 percent pure silver mixed with 7.5 percent other metal, usually copper, for strength. It is the standard mark for silver jewelry around the world and often appears as 925, .925, S925 or STERLING. The stamp does not tell you who made the piece or what it is worth. Most unsigned sterling jewelry sells close to its silver weight, which for a ring or a light chain is only a few dollars, while pieces signed by Georg Jensen, Tiffany, David Yurman, Taxco masters or known Native American silversmiths sell for far more. Stamps can also be faked on base metal, so the mark is a strong clue rather than the final word.
Quick answer
- Most unsigned 925 rings, chains and earrings are worth approximately $5-40, close to the value of the silver in them.
- Look for the maker's mark next to 925, the country or registration mark, and signs of base metal showing through wear.
- Value rises well above melt for signed designers, early Mexican Taxco silver and documented Native American work.
How to check yours, step by step
- Find the stamp. Look inside a ring band, on the tag near a necklace or bracelet clasp, on the back of a pendant bail, or on the post or clip of an earring. Use a loupe or phone macro. You are looking for 925, .925, S925, STER or STERLING.
- Read everything next to it. Maker's initials or a signature, a country name, a star with a number, an eagle, a design number or a second metal mark such as 14K or 750. These tell you more about value than the 925 itself.
- Check the wear points. Look at the inside of a ring band, the edges of a pendant and the links next to the clasp, the places that rub most. Sterling is silver all the way through, so wear shows the same white metal. Yellow, coppery or grey metal showing through means plating over something else.
- Look at the tarnish. Sterling tarnishes to a soft grey, brown or black, especially in recesses. Green or bright red stains, or skin turning green, point to brass or copper.
- Hold a magnet to it. Silver is not magnetic. A piece that snaps to a strong magnet is not sterling, though many non-magnetic base metals also exist, so passing proves little.
- Weigh it. A kitchen scale that reads in grams is enough for a melt estimate. Weigh without stones or note them, since stones and fittings add weight that is not silver.
- Compare the mark to known examples. If you see a signature such as "T & CO.", "DY" or "GEORG JENSEN", compare the font, spacing and position against genuine pieces before assuming a designer premium.
The marks you see alongside 925
| Mark | What it means | Where you see it |
|---|---|---|
| 925, .925, STERLING, STER | Sterling silver, 92.5 percent | Worldwide, the modern standard |
| S925 | Sterling, common on Asian made and modern brand jewelry | Pandora (S925 ALE), mass market pieces |
| 950 | 95 percent silver | Mexican silver, some French and Japanese work |
| 900 | 90 percent, called coin silver in the US | Older American and some Mexican silver |
| 835 | 83.5 percent | Dutch, German and Scandinavian pieces |
| 800 | 80 percent, continental silver | German, Italian and Egyptian silver |
| 999 or FINE | Pure silver | Bullion, some modern artisan work |
| Eagle with a number | Mexican assay mark, about 1948 to 1979 | Taxco and Mexico City workshops |
| Letters and number, such as TS-24 | Mexican registration code from about 1980 onward | Later Mexican silver; the letters show the city |
| Star, number and province code, such as 123 AR | Italian registered maker | Italian chains, often with 925 |
| Lion passant | British sterling standard | British silver with a date letter |
| THAI, BALI, INDIA | Country of origin | Mass produced imported sterling |
A 925 mark next to 14K or 750 on the same piece is usually fine when the gold is a separate accent, as on David Yurman designs. If both marks sit on the same part, read it with more care. Gold colored jewelry stamped only 925 is gold plated silver, often sold as vermeil.
Plated over sterling and vermeil
Sterling is still sterling when it carries a thin plating. Most modern silver jewelry is rhodium plated to slow tarnish, which gives it a bright, slightly cool white look. Vermeil is gold over sterling. In the US the term is meant for a reasonably thick layer of at least 10 karat gold over sterling. Both are valued as silver. The gold layer adds almost nothing at melt.
The reverse is the one to watch: "silver plated" means a thin silver layer over base metal, often brass or copper, and it carries no 925 mark. Plate is worth very little, and our guide on sterling silver vs silver plate covers the marks used on flatware and hollowware.
Fake 925 stamps on base metal
Stamping 925 on a brass or alloy chain costs nothing, and it is common on cheap online jewelry and market stall pieces. The clues:
- Wear shows another color. Yellow or copper at the edges of links and inside rings.
- Flaking or peeling. Real sterling does not flake. A plated surface lifting in small patches does.
- Strong magnetic pull. Sterling does not react to a magnet. A clasp spring may, so test the body of the piece.
- Too light or too heavy for its size. Silver is dense; hollow or alloy pieces often feel light.
- Green skin or green crusts. Copper heavy base metals react with skin.
- A suspiciously low price. A 30 gram chain sold new for a few dollars cannot be sterling at current silver prices.
A jeweler's acid test or an XRF reading settles it in minutes. Our guide to whether old jewelry is real gold explains the same tests for gold.
Melt value per gram
Melt value is the floor price for genuine sterling. The math is simple: weight in grams, times 0.925, times the silver price per gram.
Silver is priced per troy ounce, and one troy ounce is 31.1 grams. Assume silver is about $40 per troy ounce, which is roughly $1.29 per gram of pure silver. Silver moves daily, so check the current price before you sell. At that assumption, one gram of sterling holds about 0.925 x $1.29 = $1.19 of silver.
| Item | Typical weight | Melt at $40 per ounce | Scrap offer (70 to 90 percent) |
|---|---|---|---|
| Thin ring or pair of stud earrings | 2-4 g | $2-5 | $2-4 |
| Light chain necklace | 5-10 g | $6-12 | $4-11 |
| Pendant on a chain | 8-15 g | $10-18 | $7-16 |
| Chunky bracelet or cuff | 30-60 g | $36-71 | $25-64 |
| Heavy curb chain | 50-100 g | $60-119 | $42-107 |
| A jewelry box of mixed sterling | 200-500 g | $238-595 | $167-536 |
If silver is at $30, multiply those figures by 0.75. At $50, multiply them by 1.25. Remove stones and non-silver parts from your estimate, since buyers do.
When 925 is worth far more than melt
The maker matters more than the metal for good silver. These are the names worth looking for next to the 925.
| Maker or type | Marks to look for | Typical resale |
|---|---|---|
| Tiffany & Co. | "T & CO." or "TIFFANY & CO." with 925 | $80-400 for common pieces such as heart tags and bean pendants |
| David Yurman | "DY" or "D.Y." with 925, often with 585 or 750 | $100-400 for cable bracelets and rings |
| Georg Jensen | "GEORG JENSEN" in a dotted oval or crowned mark, design number, "925 S DENMARK" | $150-1,000, more for early or important designs |
| Mexican Taxco silver | Eagle mark, workshop number, names such as Spratling, Los Castillo, Pineda | $50-500 for good pieces; master signed work can reach the thousands |
| Native American silver | Artist hallmark or initials, sometimes unmarked on older pieces, turquoise and coral | $50-300 for typical pieces; known artists and early pawn far more |
| Scandinavian modernist | Makers such as Hans Hansen, N.E. From, David-Andersen | $80-600 |
| Pandora charms | "S925 ALE" with a crown O | $5-30 each |
| Unsigned modern sterling | 925 only, or 925 with THAI or INDIA | Melt to about $40 |
Native American jewelry has a large market for imitations, including pieces made overseas and sold as Navajo or Zuni. An artist hallmark that matches published directories, older construction and natural turquoise all support value. A piece with no history and a modern look sells closer to its silver and stone content.
Costume jewelry often gets mixed into the same drawer as sterling. Our guide on whether costume jewelry is worth anything covers the signed names in that market.
Common mistakes
- Assuming 925 means valuable. Unsigned sterling is mostly worth its weight, and a light chain holds only a few dollars of silver.
- Assuming no stamp means not silver. Older Native American and antique pieces are often unmarked.
- Calling a gold colored 925 piece gold. It is gold plated silver and prices as silver.
- Polishing heavily before selling. Collectors of Georg Jensen, Taxco and Native American silver often prefer original patina, and heavy polishing can soften marks.
- Selling signed pieces to a scrap buyer by weight. A Jensen brooch can be worth many times its melt.
- Trusting a 925 stamp on a piece that shows copper through wear. The stamp is false.
- Counting stones and clasps as silver when estimating melt.
What to photograph
- The stamp in sharp macro, lit from the side so the letters cast shadows.
- Any maker's mark or signature next to it, filling the frame.
- The whole piece on a plain background, front and back.
- The wear points: the inside of a ring, the edges of links and the clasp.
- The piece on a kitchen scale with the weight visible.
- Any original box, pouch or receipt, especially for Tiffany or Georg Jensen.
When to get it looked at in person
- A jeweler or precious metals buyer can run an acid test or an XRF reading in minutes, often without charge, and quote a scrap price. Useful for unsigned pieces where melt is the value.
- An appraiser charges roughly $50-150 per item, or an hourly rate for a box of jewelry. Worth it for signed designer pieces, larger lots or an estate that needs written values.
- A specialist dealer in Georg Jensen, Mexican silver or Native American jewelry is the right call when you see one of those marks. Dealers know the design numbers and artist hallmarks that set the price.
- An auction house with a jewelry or silver department will give an estimate on strong signed pieces at no upfront cost.
