925 Gold: What the Stamp Means and Is It Real Gold?
Vazgen Martirosov
The chain looks like gold, the seller calls it 925 gold, and the price seems almost too kind. Then you turn the clasp over, find three tiny digits and start to wonder what you actually bought.
Quick answer: 925 gold is not solid gold. The number 925 is the stamp for sterling silver, so a gold-coloured piece marked 925 is usually silver with a thin layer of gold on top. That is a fair thing to buy at a fair price. If you want gold all the way through, look for stamps like 585 or 750, the metals behind our gold necklaces and gold rings. Below: what the stamp means, what 925 Italy means, what your piece is worth and how to check it.
What does 925 mean on jewelry?
What does 925 mean on jewelry? It means 925 parts out of every 1,000 are pure silver. Divide by 10 and you get 92.5%. The other 7.5% is a stronger metal, usually copper, because pure silver is too soft for rings and chains that get worn.
The 925 stamp on jewelry can look a little different from piece to piece. You may see 925, .925, S925, Ag925, STER or STERLING. Ag is the chemical symbol for silver, so all of these point to the same metal.
What is 925 silver?
What is 925 silver? It is sterling silver, under another name. The FTC says the words silver, sterling and sterling silver describe products that contain 92.5% pure silver.
It is a real precious metal with nothing second-rate about it. It does darken with time, because silver tarnishes, but a good polish brings it back.
What does 925 mean on gold jewelry?
What does 925 mean on gold jewelry? It describes the metal underneath. A gold-coloured ring marked 925 was made from sterling silver and then given a gold surface. The number tells you nothing about that surface.
If a piece says 925 and 14K together, or 925 and 18K, read them separately. The 925 is the silver, and the karat mark only describes the gold coating. So the honest 925 gold meaning is simple: sterling silver wearing a gold coat.
Two words you will meet on these pieces:
- Gold plated: a thin layer of gold bonded to the silver. Thickness varies a lot from one maker to the next.
- Gold vermeil: a thicker coat over sterling silver. The US jewelry guides ask for gold of at least 10 karat and at least 2.5 microns thick before a piece is called vermeil.
Both are still silver inside. Vermeil simply gives the gold layer more to lose before the silver shows.
Is 925 gold real?
Is 925 gold real? The silver is real, and the coating is usually real gold too. What it is not is solid gold. The chart shows why the two get mixed up: every other stamp counts gold, while 925 counts silver.
This is where people get caught. 925 is a bigger number than 585 or 750, so it can sound like a purer gold. It is not gold at all. For every other number on that list, see our gold number code chart.
There is nothing wrong with gold-plated silver at a gold-plated silver price. The only bad deal is paying solid gold money for it.
925 Italy gold: what the stamp really means
925 Italy gold is not a type of gold. The 925 still means sterling silver, and Italy tells you where the piece was made. You will see this stamp a lot on chains.
Is 925 Italy real gold? No, not solid gold. A gold-coloured chain marked 925 Italy is generally gold over silver. A solid Italian gold chain would normally carry 585 or 750 instead. Stamps can be copied, so treat the word Italy as a claim about origin and not as proof of anything.
How to read the stamp on your piece
Read every mark, not just the number. A few extra letters can change the answer completely.
| Mark | What it means | Solid gold? |
|---|---|---|
| 925, S925, Ag925 | Sterling silver | No |
| 925 Italy | Sterling silver, made in Italy | No |
| 925 with 14K or 18K | Gold coating over sterling silver | No |
| Vermeil | Thicker gold coat over sterling silver | No |
| GP, GEP, RGP, HGE | Gold plated, often over a base metal | No |
| GF | Gold filled, a layer bonded to a base metal | No |
| 585, 14K | 58.5% pure gold | Yes |
| 750, 18K | 75% pure gold | Yes |
925 vs 585 vs 750
Here is how a gold-coloured 925 piece compares with the two solid gold stamps you see most often:
| Feature | 925 gold colour | 585 (14K) | 750 (18K) |
|---|---|---|---|
| The number counts | Silver | Gold | Gold |
| Gold in the piece | A thin surface layer | 58.5% of the weight | 75% of the weight |
| After years of wear | Gold can wear through | Colour stays | Colour stays |
| Resale value rests on | Mostly the silver | The gold | The gold |
| Best for | Trying a look | Rings worn daily | Chains, pendants |
Our guides to 585 gold and 750 gold cover those two stamps in detail.
How much is 925 gold worth?
A buyer will usually price the silver, because the gold layer holds very little metal. The sum is short:
weight in grams × 0.925 × today's silver price per gram
The price moves every day, so we do not print one here. Here is how much pure silver sits in pieces of different weights:
| Weight of the piece | Pure silver inside |
|---|---|
| 5 g | 4.6 g |
| 10 g | 9.25 g |
| 20 g | 18.5 g |
| 50 g | 46.25 g |
Silver costs far less per gram than gold, so this number lands well below what the same chain would fetch in solid gold. That is the honest answer to why a heavy 925 chain can be so cheap. Design and brand can add to the shop price, but a metal buyer rarely pays for either.
Does 925 gold fade?
Over time, yes. Gold plating wears away, and how fast depends on how thick it is and how you wear it. Rings and bracelets rub against everything, so they go first. Necklaces and earrings tend to last longer.
A silvery patch means the gold has worn through. A dark patch usually means the silver beneath is tarnishing. A little care slows both down:
- Keep it dry. Take it off for the shower, the pool and the gym.
- Perfume first. Put on lotion and perfume, let them dry, then put on the piece.
- Clean it gently. Use a soft cloth, and warm soapy water if needed. Skip polishing cloths, which can rub the coating away.
- Store it apart. A soft pouch stops harder pieces from scratching it.
When the colour does go, a jeweller can often replate the piece. Solid gold never needs this for its colour, because yellow gold has no layer to lose.
How to check a piece marked 925
A stamp is cheap to buy, so treat it as a claim. These steps will tell you most of what you need to know:
- Read the whole mark. Use your phone's camera zoom and good light. Check for 925 alongside any karat mark or plating letters.
- Inspect the worn spots. Look at the clasp, the edges and the inside of a band. A pale silver colour showing through means plating.
- Think about the price. Solid gold is priced by its weight in gold. A heavy gold chain at a very low price is telling you something.
- Try a magnet. Silver and gold are not magnetic. A strong pull means a base metal somewhere, though no pull does not prove the metal is good.
- Ask for a real test. A jeweller or assay office can tell you what the metal is. Mention the 925 stamp, so they test below the surface and not just the coating.
We walk through the safe home tests, and the ones to skip, in how to tell if gold is real.
Looking for gold all the way through?
We do not make 925 pieces. We have been working in Yerevan since 2010, and everything we make is solid gold: 14K for rings and pendants like the half eternity ring, and 18K for our fine gold chains.
You are welcome to have anything we make tested at an assay office, so the number is never just our word.
Frequently asked questions
Is 925 real gold?
No. 925 is the mark for sterling silver, which is 92.5% pure silver. A gold-coloured piece stamped 925 has real silver inside and usually a thin layer of real gold on top.
Is 925 gold worth anything?
Yes, but mostly for its silver. A metal buyer works from the weight and the silver price, and the coating adds very little. It will not fetch anything close to the price of solid gold.
Is 925 better than 14K gold?
They are different things. 925 is silver, usually with a gold coating, while 14K is solid gold at 58.5% purity. 925 costs far less, and 14K keeps its colour and holds more value.
Does 925 gold tarnish?
The gold layer does not tarnish much, but the silver under it can, especially once the coating wears thin. Keep the piece dry and away from perfume, and store it in a soft pouch.
Will 925 gold turn my skin green?
It can, once the coating wears through. Sterling silver contains a small amount of copper, and copper can leave a green mark on some people's skin. The mark washes off.
Can you wear 925 gold every day?
You can, but expect the colour to fade sooner on a ring or bracelet than on a necklace. Take it off for swimming, the gym and cleaning. For a ring you plan to wear for years, solid gold is the safer choice.
Can 925 gold be replated?
Usually, yes. A jeweller can clean the piece and add a new gold layer. Compare the cost with the value of the piece first, since a low-priced item may not be worth it.
Can a piece be stamped 925 and 14K?
Yes, and it means gold over silver. The 925 describes the sterling silver base and the 14K describes the gold coating. It is not solid 14K gold.
Back to the clasp
So those three digits were telling the truth all along. They were just talking about the silver. 925 gold is a pretty, affordable way to wear the colour of gold, as long as you know what you are paying for. And if you would rather have gold that goes all the way through, the stamp to look for has a different number on it.
