Gold Jewelry Marks: What '750' Means for Purity

If you’ve ever seen a “750” stamp on gold jewelry, you might be wondering what it means. In simple terms, 750 gold means 18K gold, which contains 75% pure gold and 25% other metals. In this guide, we’ll explain everything about 750 gold, its purity, value, and whether it’s worth buying.

If you've ever flipped over a gold ring or necklace and spotted the number 750 stamped inside, you've found one of the most important hallmarks in fine jewelry. It's not a serial number, a size code, or a random factory mark it's a purity stamp that tells you exactly what you're holding.

This guide breaks down everything the 750 hallmark means, how it compares to other gold types, and what it's actually worth.

What Does 750 Mean on Jewelry?

The 750 stamp on jewelry means the piece contains 75% pure gold. The number comes from the European millesimal fineness system, where gold purity is expressed in parts per thousand. So 750 means 750 out of 1,000 parts are pure gold  the remaining 25% is an alloy of metals like silver, copper, or palladium, added to improve durability and color.

You'll find this stamp on rings, necklaces, bracelets, and earrings sold across the US, UK, Europe, and Asia. It's one of the most recognized gold purity marks in the world.

Is 750 Real Gold?

Yes  750 gold is absolutely real gold. In fact, it's one of the highest purity levels available in fine jewelry. At 75% pure gold content, it's considered premium-grade and sits just below 999 (pure gold) and 916 (22K gold) in the purity hierarchy.

What makes 750 gold practical is the 25% alloy mix. Pure gold (999 or 24K) is too soft for everyday wear  it bends, scratches, and loses shape quickly. The alloy in 750 gold adds just enough strength to make it wearable without sacrificing the rich, warm color that makes gold so desirable.

How Many Karats Is 750 Gold?

750 gold is 18 karat (18K) gold. Here's the simple math: the karat system divides gold purity into 24 parts. Multiply 18 by 24, then divide by 24  or simply note that 18/24 = 0.75, which equals 75% pure gold, or 750 in millesimal fineness.

18K/750 is the sweet spot that most fine jewelry designers and luxury brands prefer — pure enough for deep color, strong enough for lasting wear.

750 Gold vs 585 Gold

750 gold (18K) and 585 gold (14K) are both genuine gold, but they differ in purity, color, and price.

• Purity: 750 gold is 75% pure; 585 gold is 58.5% pure.

• Color: 750 gold has a richer, more saturated yellow gold tone. 585 gold is slightly paler due to the higher alloy content.

• Durability: 585 gold is actually slightly harder and more scratch-resistant because of its higher alloy ratio — making it a solid choice for daily-wear pieces.

• Price: 750 gold costs more per gram because of the higher gold content.

• Skin sensitivity: Both are generally hypoallergenic, but 750 gold is the better choice for those with metal sensitivities since it contains less alloy.

If you're shopping for an engagement ring or fine jewelry you'll wear every day, both are excellent options. 750 gold wins on luxury feel; 585 offers better value and durability.

What Does 750 Stamp Gold?

The 750 stamp is an official purity hallmark, certifying that the gold meets the 18K standard. In countries with mandatory hallmarking laws  like the UK and much of Europe  this stamp is applied by an assay office after independent testing. In the US, the stamp is applied by the manufacturer and is regulated under the National Gold and Silver Stamping Act.

You may also see the 750 stamp alongside other marks, such as:

• A maker's mark (the manufacturer or brand)

• A date letter (indicating the year of hallmarking, common in the UK)

• An assay office mark (the testing authority)

Together, these stamps form a complete provenance record for the piece.

Is 750 Gold Worth Anything?

Yes — 750 gold holds significant value. Because it contains 75% pure gold, its worth is directly tied to the spot price of gold, which fluctuates daily on global markets. In practical terms, 750 gold is one of the most valuable jewelry grades you'll encounter in the retail market.

Beyond melt value, 750 gold jewelry often carries additional worth based on craftsmanship, brand, age, and gemstone content. Branded or designer pieces in 750 gold can command premiums well above their raw metal value.

If you're buying 750 gold as an investment or resale piece, it retains value reliably over time  better than lower-karat gold, which has more alloy diluting its worth.

What Is AU750 Gold?

AU750 is simply another way of writing the 750 hallmark  "AU" is the chemical symbol for gold (from the Latin aurum). So AU750 and 750 mean exactly the same thing: 18K gold with 75% purity.

You'll sometimes see this stamp on jewelry from Asian markets, particularly pieces manufactured in China, Hong Kong, and Japan. It carries the same legal and market value as a standard 750 stamp. If you spot AU750 on a piece, you're looking at genuine 18K gold.

What Does Italy 750 Mean on Jewelry?

Italy 750 means the piece is 18K gold manufactured in Italy. Italy has long been one of the world's premier gold jewelry manufacturing hubs  regions like Vicenza, Arezzo, and Valenza are globally renowned for their craftsmanship. Italian 750 gold follows the same purity standard (75% pure gold) but is also associated with high-quality workmanship and refined design.

Italian gold jewelry often includes both the 750 purity stamp and the Italian assay office mark, a small star symbol that serves as an additional quality guarantee. When you see "Italy 750," you're getting both the metal quality of 18K gold and the craftsmanship heritage of Italian jewelry-making.

How to Tell If 750 Gold Is Real?

Here are the most reliable ways to verify 750 gold authenticity:

1. Look for the hallmark. Check clasps, inner bands, or the back of pendants for the 750, 18K, or AU750 stamp. Legitimate pieces will always carry this mark.

2. Magnet test. Real gold is not magnetic. If the piece sticks to a strong magnet, it's not genuine gold (or has significant ferrous metal content).

3. Acid test. A jeweler can apply nitric acid to a small scratch on the piece. Real 18K gold won't react. This is the most definitive at-home/jeweler method.

4. Electronic tester. Professional jewelers use electronic gold testers that measure conductivity to confirm karat rating quickly and non-destructively.

5. XRF analysis. The gold standard (pun intended)  X-ray fluorescence testing gives a precise, non-destructive breakdown of the metal's composition. Many reputable jewelers offer this service.

Avoid: The "bite test"  it's inaccurate and can damage the piece or your teeth.

How Much Is 750 Gold Worth?

The value of 750 gold is based on its gold content relative to the current spot price. To calculate:

Formula: Weight (grams) × 0.75 × Current gold price per gram = Melt value

For example, if gold is trading at $90 per gram and you have a 10-gram 750 gold bracelet: 10 × 0.75 × $90 = $675 melt value

Keep in mind this is just the raw metal value. Retail jewelry prices are higher due to craftsmanship, design, brand markup, and any gemstones. When selling to a buyer or pawn shop, you'll typically receive 70–85% of the melt value.

Gold prices fluctuate daily  always check the live spot price before making a buy or sell decision.
