What Does "750" Mean on Jewelry?
Ever noticed "750" stamped on a ring or necklace and wondered what it means? This tiny number carries big importance. Misunderstanding it can lead to buying fakes, overpaying, or missing out on real value. Here, we'll break it down simply-so you know exactly what you're holding.
What Does "750" Gold Mean?
The "750" mark on jewelry tells you the piece is 18K gold, made of 75% pure gold and 25% alloy metals like copper, silver, or palladium. This balance makes it stronger than 22K or 24K, yet richer in color than 14K.
Unlike plated or layered jewelry, 750 gold is solid throughout-not just a surface coating. That means its beauty and value last much longer, and it will always retain a significant portion of real gold content.
This is why luxury houses such as Cartier, Tiffany & Co., and Bvlgari rely on 750 gold as their standard. It offers the best of both worlds: luxurious purity with durability for daily wear.
Understanding 750 Gold Purity: Karat System & EU Standards
The Karat System
Gold purity is measured in karats. Pure gold is 24K (99.9%), but it's too soft for daily wear. That's why jewelers mix it with alloys, creating stronger versions like 22K, 18K, and 14K.
The 750 stamp specifically means 18K gold-75% pure gold blended with 25% alloy metals. This mix gives jewelry the rich color of high gold content while keeping enough durability for everyday wear.
| Mark | Purity (%) | Common Use |
|---|---|---|
| 999 (24K) | 99.9% | Investment bars, cultural gold |
| 916 (22K) | 91.6% | Traditional jewelry, Asia & Middle East |
| 750 (18K) | 75% | Fine jewelry, luxury brands, engagement rings |
| 585 (14K) | 58.5% | Everyday fine jewelry, Western markets |
| 417 (10K) | 41.7% | Budget jewelry, US-focused market |
This is why 750 gold is considered the global sweet spot-it combines luxury-grade purity with resilience, making it the standard for fine jewelry and premium brands.
EU Standards for 750 Gold
In the European Union, gold fineness is expressed in parts per thousand (‰). The number 750 confirms 75% pure gold content, officially recognized as 18K.
By law, jewelry marked "750" must be tested by an official assay office and hallmarked. Many EU countries also follow the Common Control Mark (CCM) system, meaning a certified piece in one country is legally accepted across others.
This makes "750" more than just a stamp-it is a legal guarantee of authenticity, purity, and compliance throughout Europe.
750 Gold vs. Common Alternatives
| Feature | 750 Gold (18K) | Gold Filled | Gold Vermeil | Gold Plated |
|---|---|---|---|---|
| Composition | 75% solid gold alloy | Brass core + thick gold layer | Sterling silver + gold plating | Base metal + thin gold coat |
| Durability | Excellent – lifelong | Good, wears with time | Moderate | Low, fades quickly |
| Resale Value | High | Low | Low–moderate | Very low |
| Stamp Example | 750 | 1/20 14K GF | 925 + GP | GP / HGE |
Why it matters: Only genuine 18K gold jewelry is stamped with 750. Other materials may look similar at first glance but lack the same durability, hypoallergenic safety, and resale value.
Stamp examples based on hallmarking regulations and guidelines from the European Union Hallmarking Convention, UK Assay Offices, and U.S. FTC Jewelry Guides.
Global Regulations and Hallmark Standards
The "750" hallmark isn't just a number-it's a legal guarantee in many markets. Around the world, strict rules exist to ensure jewelry stamped "750" is truly 18K gold.
United Kingdom
Under the Hallmarking Act 1973, all gold items over 1 gram must be assayed and stamped by an official assay office. For 18K gold, the official fineness mark is 750, often combined with a maker's mark and an assay office symbol.
France & EU Members
In France, 18K gold is marked with the eagle's head symbol. Across the European Union, gold fineness is expressed in parts per thousand, so "750" legally means 75% gold content. Many countries also use the Common Control Mark (CCM), allowing a piece hallmarked in one member state to be legally recognized in others.
United States
In the U.S., hallmarking isn't legally required, but the Federal Trade Commission (FTC) regulates how gold must be described. Reputable jewelers stamp "750" or "18K" on genuine 18K gold jewelry to ensure clarity for consumers.
Compliance and Safety
The EU's REACH regulations set strict limits on nickel release, lead, and cadmium in jewelry. That means any 750 gold jewelry sold in Europe must not only meet purity standards but also be safe for skin contact.
Why it matters: These hallmarking systems protect both buyers and sellers. When you see 750 on jewelry from a certified source, you can trust it's authentic 18K gold-recognized by international law and safe to wear.
Market & Value Factors for 750 Gold
The value of 750 gold jewelry goes beyond its gold content. Several factors shape its price and desirability in today's market:
Gold Market Prices
The global gold price changes daily based on supply, demand, and the strength of the U.S. dollar. In recent years, gold has reached record highs, and many analysts expect prices to remain strong. This directly affects the cost of manufacturing and buying 18K jewelry.
Craftsmanship and Design
Two identical pieces of 750 gold may carry very different price tags. Intricate designs, stone settings, or custom-made details increase the value far beyond raw material costs. For luxury houses, design often doubles or triples the final price.
Brand Reputation
A simple 750 gold ring from a generic manufacturer may sell close to its material value, while the same weight in a Cartier or Tiffany piece commands a major premium. Brand trust and heritage significantly influence resale and retail pricing.
Resale and Recycling Value
High gold prices also make second-hand markets stronger. Old 750 gold jewelry can be sold, melted down, or recycled at a value much closer to its original purchase price compared with plated or gold-filled items, which have almost no resale worth.
Alternatives on the Rise
Because gold costs keep climbing, many jewelers now promote vermeil or gold-filled jewelry as lower-cost alternatives. However, these options do not carry the same durability or resale value as genuine 750 gold, making them less attractive for long-term buyers.
While global gold prices set the baseline, craftsmanship, branding, and recycling potential make 750 gold one of the most stable and investment-worthy choices in the jewelry world.
Where You'll Commonly See 750 Stamped Jewelry
The 750 stamp is frequently found on:
- Wedding and engagement rings
- High-end gold chains and pendants
- Designer earrings and cufflinks
- European and Middle Eastern gold jewelry
- Custom fine jewelry from boutique brands
Luxury brands like Cartier, Tiffany & Co., and Bvlgari commonly use 750 as their gold standard, especially in items marketed as 18k gold jewelry.
Keep in mind, some gold filled jewelry may resemble the tone of 18k gold, but will never carry a 750 stamp unless it's misrepresented.
Can 750 Gold Jewelry Cause Allergies?
750 gold (18K) is made of 75% pure gold and 25% other metals. Pure gold itself is hypoallergenic, but the added alloys may cause reactions in sensitive skin.
Copper and silver are usually safe, but if nickel is used in the mix, it can trigger irritation for those with nickel allergies.
For most people, 18K gold is comfortable and safe to wear every day. Still, if you know you have sensitive skin, always choose nickel-free certified jewelry for extra peace of mind.
When buying 750 gold jewelry, ask your jeweler or supplier for allergy-safe certifications-it's the easiest way to avoid surprises.
Can You Shower with 750 Gold Jewelry?
Yes, you can shower with 750 gold (18K), but it's not the best choice if you want your jewelry to stay bright.
Shampoo, conditioner, and soap can leave residue that dulls the surface. Hot water and steam may also weaken delicate settings over time.
An occasional shower won't ruin your jewelry, but daily exposure can speed up wear and reduce its shine.
To keep your 750 gold pieces looking their best, it's safer to remove them before showering. And not just for showers-we also don't recommend wearing them while swimming or in similar conditions.
How to Verify Authentic 750 Gold
The "750" stamp means 18K gold, but counterfeit marks exist. Quick ways to check:
- Hallmark – Clear "750" with maker's or assay mark.
- Professional Test – Jewelers use acid or electronic tools to confirm purity.
- Weight & Color – Real 750 gold feels dense and keeps its rich tone.
- Source – Always buy from certified wholesalers or trusted retailers.

Care & Storage for 750 Gold Jewelry
Even though 750 gold is durable, the right habits keep it shining and safe for decades. Here's what to do in different situations:
When You're Not Wearing It
- Store each piece separately in a soft pouch or lined box.
- Avoid tossing chains or rings together-they can scratch or tangle.
- Keep jewelry in a dry place; moisture and humidity can dull the shine over time.
When It Needs Cleaning
- Mix warm water with mild soap, gently wipe with a soft cloth.
- For detailed areas, use a soft-bristle brush.
- Avoid bleach, chlorine, or harsh cleaners-they damage gold alloys and loosen stones.
When You're Wearing It
- Take it off before swimming-the chlorine in pools and salt in seawater can weaken gold over time.
- Remove before sports or gym workouts; sweat and impact can scratch or bend pieces.
- Don't wear while handling cleaning products or perfumes-chemicals can tarnish or dull the surface.
With a little care, 750 gold jewelry can stay as bright as the day you bought it. If you'd like more detailed care routines for different metals and gemstones, we've put together a separate guide you can explore.
