You find a tiny 750 stamped inside a ring, on the clasp of a necklace, or on the back of a piece of jewelry.
So what does 750 mean on gold?
750 means the jewelry is 75% pure gold. That is the same purity as 18-karat gold, commonly written as 18K.
In simple terms:
750 gold = 75% pure gold = 18K gold
The remaining 25% consists of other metals added to make the jewelry stronger and to change its color or other characteristics.
So if your jewelry is marked 750, you may have a valuable piece of real gold.
Is 750 Gold Real Gold?
Yes. 750 gold is real gold.
Pure gold is extremely soft, which makes 24K gold less practical for many types of everyday jewelry.
By mixing gold with other metals, jewelers can make pieces that are stronger and more resistant to wear.
With 750 gold:
- 75% is pure gold
- 25% is other metals
- It is equivalent to 18K gold
That makes 750 considerably more gold-rich than the 10K and 14K jewelry commonly found in the United States.
Why Does 750 Mean 18K Gold?
There are two common ways of describing gold purity.
The Karat System
The karat system measures gold out of 24 parts.
For 18K gold:
18 ÷ 24 = 0.75
That means 18K jewelry contains 75% pure gold.
The Fineness System
The fineness system measures purity out of 1,000 parts.
750 ÷ 1,000 = 75%
That is why a 750 stamp and an 18K stamp essentially describe the same gold purity.

Common Gold Markings on Jewelry
Once you understand 750, many other gold stamps become easier to read.
| Gold Marking | Karat | Approx. Gold Purity |
|---|---|---|
| 417 | 10K | 41.7% |
| 585 | 14K | 58.5% |
| 750 | 18K | 75% |
| 916 | 22K | 91.6% |
| 999 | 24K | 99.9% |
So when you see 750 inside a piece of jewelry, think:
750 = 18K = 75% Gold
Where Is the 750 Stamp Usually Found?
Gold markings are often tiny and placed somewhere they will not affect the appearance of the jewelry.
Check:
- Inside the band of a ring
- On a necklace clasp
- Near the clasp of a bracelet
- On the post or back of an earring
- On the back of a pendant
- On a small tag attached to a chain
A magnifying glass or your phone’s camera zoom can make the marking much easier to see.

Does 750 Gold Have to Be Yellow?
No.
750 describes purity, not color.
You may find:
750 Yellow Gold
Usually made by combining gold with metals such as silver and copper.
750 White Gold
Still contains 75% gold but uses different alloy metals to produce a whiter appearance.
750 Rose Gold
Contains 75% gold with a metal mixture that typically contains more copper, producing its pink or reddish color.
All three can legitimately be marked 750.
Is 750 Gold Better Than 585 Gold?
750 gold contains considerably more pure gold than 585 gold.
585 gold = 14K = 58.5% gold
750 gold = 18K = 75% gold
If two pieces weigh exactly the same, the 750 piece contains more pure gold and therefore normally has a higher precious-metal value.
For example, a 10-gram piece of 750 gold contains approximately:
10 grams × 75% = 7.5 grams of pure gold
A 10-gram piece of 585 gold contains approximately:
10 grams × 58.5% = 5.85 grams of pure gold
That’s a significant difference.
How Much Is 750 Gold Worth?
The value of 750 gold depends mainly on:
- The weight of the item
- Its actual gold purity
- The current gold price
For basic melt-value calculations:
Weight in grams × 0.750 × current pure-gold value per gram
For example, if you have a 20-gram 750 bracelet:
20 × 0.750 = 15 grams of pure gold
The piece therefore contains approximately 15 grams of actual gold before considering stones, non-gold components, testing results, or other factors.
Because the gold market changes throughout the day, avoid relying on an old chart or article for today’s value.

Does a 750 Stamp Guarantee the Jewelry Is Real?
No.
A stamp is a very good clue, but it is not absolute proof.
Fake and gold-plated jewelry can sometimes contain misleading markings.
The opposite is also true: jewelry without a visible stamp is not automatically fake.
Stamps can:
- Wear away
- Become difficult to read
- Be removed during repairs
- Be missing from older jewelry
- Be located somewhere difficult to find
Professional gold testing is the best way to determine the actual gold content.
Can a Fake Gold Piece Be Stamped 750?
Unfortunately, yes.
A dishonest manufacturer can stamp almost anything onto a piece of metal.
That is why you should never determine the value of an expensive piece of jewelry from the stamp alone.
If you’re unsure whether a piece marked 750 is actually gold, read our guide on how to tell if gold is real or have it professionally tested.
What If My Jewelry Says 750 but Tests Lower?
The stamp tells you what the jewelry was represented to contain.
Testing tells you what the metal actually contains.
Depending on the item, repairs, solder, mixed components, plating, or an inaccurate stamp can affect the test results.
When selling gold, the actual gold content is ultimately more important than the number stamped on the jewelry.
Is 750 Gold Valuable?
Absolutely.
Because 750 gold contains 75% pure gold, even relatively small pieces can contain a meaningful amount of precious metal.
You may have valuable 750 gold sitting in a jewelry box without realizing it.
Common examples include:
- Rings
- Wedding bands
- Bracelets
- Necklaces
- Chains
- Earrings
- Pendants
- Broken jewelry
- Estate jewelry
- Designer jewelry
- Jewelry inherited from family members
And remember:
Broken 18K jewelry still contains gold.
A broken clasp or damaged chain does not make the gold itself disappear. Gold Kings buys many types of gold jewelry and precious metals, including broken and unwanted pieces.
