Are you wondering what the quality standards are for gold used in jewelry in France? It's an excellent question, because it's important to know what you're buying, especially when it's an investment or a precious object. Between carats, hallmarks, and the different types of gold, it's easy to get lost. Don't worry, I'm going to shed some light on the rules that govern gold in the world of French jewelry. We'll look together at how to ensure that the piece of jewelry you're considering meets the quality standards.
Key Takeaways
- In France, the purity of gold in jewelry is necessarily measured in thousandths (for example, 750 thousandths for 18 carats), and no longer in carats.
- Hallmarks are essential for authenticating the quality and gold content of a piece of jewelry. The state hallmark guarantees the legal fineness.
- A distinction must be made between solid gold ('in gold'), gold plating (gold layer of at least 3 microns) and gold-plated gold (gold layer less than 3 microns), which have very different values and standards.
- Vermeil is a specific term for 925 silver covered with a layer of 750 thousandths gold of at least 5 microns.
- The color of gold (yellow, pink, white) depends on the alloy used with other metals, and not on its intrinsic quality.
Understanding gold purity and carats in jewelry
When you look at a gold piece of jewelry, you might wonder where its color and shine come from, and above all, how to tell if it's a real treasure or a fake. That's where the concepts of fineness and carats come in. They give you a precise idea of the amount of pure gold contained in the piece.
Measuring the purity of gold: carats and thousandths
To talk about the purity of gold, we mainly use two systems: carats and thousandths. You're probably familiar with the carat system; it's a scale from 1 to 24. A 24-carat gold piece of jewelry is pure gold, 100% gold. But be careful, in jewelry making, pure gold is rarely used because it's too soft and would easily deform. Imagine your favorite ring turning into a flat disc at the slightest bump! Not ideal.
This is why alloys are used, meaning that pure gold is mixed with other metals such as silver, copper, or zinc. These mixtures provide strength and allow for a variety of colors. To be more precise and avoid any confusion, France primarily uses the system of thousandths. This is a measurement in parts per thousand (‰). For example, a piece of jewelry marked "750" means that it contains 750 thousandths of pure gold, or 75% gold. This is the equivalent of 18-karat gold.
Here is a small table to help you see things more clearly:
| Title in Carats | Title in Thousandths | Percentage of Pure Gold |
|---|---|---|
| 24 carats | 999‰ (or 1000‰) | Up to 99.9% |
| 18 carats | 750 ‰ | 75% |
| 14 carats | 585 ‰ | 58.5% |
| 9 carats | 375 ‰ | 37.5% |
The different gold standards permitted in jewelry
In France, three gold purities are primarily authorized and used for jewelry making: 18-karat gold (750‰), 14-karat gold (585‰), and 9-karat gold (375‰). 24-karat gold (999‰), although pure gold, is too malleable for everyday jewelry use. It is generally reserved for investment purposes in the form of bars or coins.
- 18 carat gold (750‰) This is the most common and popular title in France and Europe. It offers an excellent balance between pure gold content (75%) and durability thanks to the alloy. It retains a beautiful color and resists wear well.
- 14 carat gold (585‰) Less pure than 18-karat gold (58.5%), it is more durable and often more affordable. It is commonly found in high-end costume jewelry and in some countries, such as the United States.
- 9 carat gold (375‰) With only 37.5% pure gold, it is the cheapest and most durable grade. It is more common in English-speaking countries. Its color may be less intense, and it may be more prone to allergic reactions in those with sensitive skin.
The importance of the alloy for durability and color
As I was saying, pure gold is too soft. Alloys are the secret to creating jewelry that lasts and comes in a variety of colors. By mixing gold with different metals, you can achieve magnificent shades.
- Yellow gold It is the classic mixture of pure gold with silver and copper. The proportion of each metal influences the hue, ranging from pale yellow to a deeper yellow.
- White gold Obtained by combining pure gold with white metals such as palladium, nickel, or manganese. It is often rhodium-plated (coated with a thin layer of rhodium) to give it a bright white shine and protect it.
- Rose or red gold : These warm hues are obtained by increasing the proportion of copper in the alloy with pure gold.
The alloy isn't just about strength; it's also what gives the piece of jewelry its unique character and color. It's a bit like the jeweler's secret recipe!
So, when you choose a piece of jewelry, pay close attention to its title. This tells you how much gold it contains and, indirectly, its value and quality.
Hallmarks and certificates: guarantees of gold quality

When you buy a piece of gold jewelry, you want to be sure of what you're getting, right? That's where hallmarks and certificates come in. They're a bit like your jewelry's identity cards, telling you exactly what it contains and who made it.
The essential role of hallmarks in authenticating gold
Imagine a small stamp, almost invisible to the naked eye, but incredibly important. That's a hallmark. It's engraved directly onto the precious metal, and there are several types. The most important one for you is the hallmark, also called the fineness hallmark. It tells you the purity of the gold at a glance. In France, for gold, you'll often see:
- Eagle head : for 18 carat gold (750 thousandths).
- Eagle head (smaller): for 14 carat gold (585 thousandths).
- Eagle head (even smaller): for 9 carat gold (375 thousandths).
There is also the maker's mark, which is like the signature of the creator or seller. It is usually diamond-shaped and unique to each craftsman. It serves as an additional guarantee of the origin and the seller's responsibility.
It's important to know that these hallmarks aren't just for show. They're legally required for most precious metal jewelry, unless the pieces are so small or delicate that they can't withstand the hallmark without being damaged. It's a protection for you, to avoid any unpleasant surprises.
The certificate of authenticity: a contract of conformity
Sometimes, a piece of jewelry can be so light or delicate that it isn't hallmarked. Don't panic! In this case, the seller is obligated to provide you with another document: a certificate of authenticity, or a detailed invoice that includes all the important information. This certificate is essentially a contract between you and the seller. It must clearly state:
- Description of the jewelry.
- The fineness of the gold (in carats or thousandths).
- The color of gold (which depends on the alloy).
- The total weight of the jewelry.
- If stones are present, their type and weight.
- The date of issue of the certificate.
- And sometimes, even the origin of the gold.
It's legal proof that confirms what you're buying matches the description. It gives you real security about your purchase.
What should you do if a piece of jewelry does not have a hallmark?
As I was saying, there are exceptions. If a piece of jewelry doesn't have a hallmark because it's too light, the seller must be able to provide you with a certificate of authenticity or a detailed invoice. It's the law that requires them to do so. If you're buying secondhand jewelry, always ask for these documents. If you're buying from a reputable professional, they should provide them without you having to ask. If you have any doubts, don't hesitate to ask questions. A good jeweler will always be transparent about the quality of their pieces.
International standards for investment gold
When it comes to investment gold, the rules of the game differ somewhat from those of jewelry. It's no longer just about aesthetics or how the metal looks on a daily basis, but primarily about its purity and its recognition on global markets. For you, as an investor, this means looking at very specific standards that guarantee the value and ease of resale of your gold.
The LBMA 'Good Delivery' standard
The London Bullion Market Association (LBMA) acts as a kind of quality control body for professionally traded gold and silver. For a gold bar to be considered top-quality investment gold, it must meet the criteria of the "Good Delivery" standard. This is somewhat like an international quality seal. Gold bars that meet this standard are accepted without question on global markets, which is quite reassuring when you want to sell your gold later.
The main characteristics of a "Good Delivery" ingot are:
- Purity: It must have a gold content of at least 99,5% (often 99,9% or even 99,99% for modern ingots).
- Weight: The reference ingots for central banks weigh approximately 400 ounces (or 12,5 kg), but the standard also applies to smaller formats such as 1 kg, 250 g, 100 g, etc.
- Maker : It must be produced by a refiner accredited by the LBMA. There is an official list of these recognized refiners.
- Identification : Each ingot must bear a unique number, the refiner's name, the fineness (purity), and the weight. It is often sealed in a security blister pack with a certificate of authenticity.
The LBMA sets the highest standards for the refining and storage of precious metals, thereby ensuring confidence in the international market.
The characteristics of a certified gold bar
When you buy investment gold, you usually receive a certificate of authenticity. This document is your guarantee. It certifies that the gold bar you hold is indeed what it claims to be. You will find key information on it, such as:
- The exact weight of the ingot.
- Its purity (for example, 999,9‰, which corresponds to 24 carats or 99,99% pure gold).
- The unique identification number of the ingot.
- The name of the refiner or manufacturer.
- The date of manufacture or testing.
This certificate, often included in the ingot's security blister pack, is essential. It proves the ingot's conformity to international standards and facilitates its resale. Without this certificate, or if the ingot is not recognized by the standards, its value can be significantly reduced.
Recognized manufacturers and their certifications
To ensure the quality of your investment gold, it's best to choose bars produced by internationally recognized refiners accredited by the LBMA. Among the most well-known are companies like C-Hafner, Metalor, Heraeus, Umicore, and Heimerle + Meule. These manufacturers adhere to very strict production processes to guarantee the purity and quality of their products. Purchasing from these brands ensures your gold will be accepted on the global market without any issues. It's always wise to verify that the manufacturer's name on the bar corresponds to one of these reputable companies.
Gold used in France: specific characteristics and regulations
In France, gold used in jewelry is subject to strict regulations to guarantee quality and protect the consumer. It's not simply a matter of taking any metal and shaping it. There are standards to be met, and that's a good thing, isn't it?
The requirement to use the title in thousandths
You may have already seen jewelry marked in carats, like 18 carats. Well, in France, since January 1, 1995, that's no longer the case for sales. We now use the system of thousandthsThis is a more precise measurement that indicates the proportion of pure gold in an alloy. For example, 750 parts per thousand means that the piece of jewelry contains 75% pure gold. That's clearer, isn't it? It avoids confusion with carats, which are also used for precious stones.
Here's a quick summary to help you find your way around:
- 375 thousandths gold (9 carats): 37,5% pure gold. This is the minimum for a piece of jewelry to legally be called "gold" in France.
- 585 thousandths gold (14 carats): 58,5% pure gold.
- 750 thousandths gold (18 carats): 75% pure gold. This is the most common purity and is often considered an excellent compromise between purity, durability, and color.
- 916 thousandths gold (22 carats): 91,6% pure gold. Less common in classic French jewelry, more used for certain pieces or in other cultures.
- 999 thousandths gold (24 karat): 99,9% pure gold. This is the purest form of gold, but it is very soft and easily deformed. It is mainly found in the form of investment bars, not really for everyday jewelry.
The different types of gold: 'pure gold', 'gold-plated', 'gold-gilded'
Be careful, you must distinguish between the different names. Just because something is shiny doesn't mean it's the same thing:
- In gold This refers to jewelry made with a gold alloy that meets legal standards (375, 585, 750 parts per thousand, etc.). This is what we mean when we buy jewelry made of genuine gold.
- Gold plated Here, we have a base made of a non-precious metal (like brass or copper) which is covered with a thin layer of gold. French law requires that this gold layer have a minimum thickness of 3 microns and be at least 18 karats (750 parts per thousand). It's a more affordable alternative, but it's not solid gold.
- Gold-plated This is a lighter finish, often a thinner layer of gold than gold plating. The thickness is not regulated in the same way, and the quality can vary. One should be wary of this designation.
The status of vermeil and its legal designation
Le ruddy This is a somewhat unique case. It involves solid silver (at least 925 parts per thousand) coated with a layer of gold at least 5 microns thick and with a minimum purity of 18 carats (750 parts per thousand). This is an ancient technique that gives silver a golden appearance while being more durable than simple plating. Legally, the term "vermeil" is protected and guarantees this specific composition. It's therefore a great option if you're looking for a piece of jewelry with a gold finish but a high-quality silver base.
Gold in French jewelry: beyond investment
When we think of gold, we often picture ingots or investment coins, those safe-haven assets that weather crises. But gold is also, and above all, the raw material of jewelry, the one that makes your favorite pieces shine. In France, the use of gold in jewelry follows precise rules, but goes far beyond simple financial speculation.
Gold as the main raw material in jewelry
Gold is the undisputed king of jewelry. Its exceptional malleability allows artisans to shape it into creations of incredible finesse. It is found in almost all jewelry, whether rings, necklaces, bracelets, or earrings. Its nobility and durability make it a material of choice for pieces that one wishes to keep for a lifetime, or even pass down.
The color of gold: a question of alloy and aesthetics
Pure gold, also called 24-karat gold, is a very intense yellow, but it is also very soft. To make it more durable and give it different hues, it is mixed with other metals. This is where the magic of alloying comes in:
- Yellow gold: It is the classic mixture of fine gold with silver and copper. The proportion of these metals determines the exact shade.
- Rose gold: This warm color is obtained by increasing the proportion of copper in the alloy.
- White gold: To achieve this silvery hue, yellow gold is alloyed with metals such as palladium or nickel, then often rhodium-plated for maximum shine.
It is important to note that the color of gold is not an indicator of its purity. A piece of jewelry made of 18-karat white gold is just as pure as a piece of jewelry made of 18-karat yellow gold.
The traceability and origin of the gold used
Today, the origin of gold is a growing concern. Consumers are paying increasing attention to the source of the precious metals they buy. French jewelers are increasingly committed to traceability, favoring recycled gold or gold sourced from responsible mines. This not only guarantees an ethical and environmental approach, but also ensures the quality and purity of the gold used in your jewelry. Knowing where the gold in your jewelry comes from gives you the assurance of a piece made with respect for people and the planet.
The gold used in French jewelry is therefore much more than a simple investment. It is a noble metal, expertly crafted to create objects with strong sentimental and aesthetic value. The color, durability, and even the origin of this gold are all factors that contribute to the beauty and quality of the jewelry you wear.
Gold in French jewelry is much more than simply a way to make money grow. It's an art, a history, a craft that transcends time. Each piece tells a story, embodying a timeless beauty that captivates far beyond its material value. Consider the exquisite details, the unique brilliance that never goes out of style. It's this magic we celebrate. Curious to learn more? the value of these treasures Visit our website to discover how we evaluate and showcase these magnificent creations.
In conclusion: your gold, a matter of trust

It's your right as a buyer, and it ensures you have an item in your hands that truly matches what you paid for. After all, gold is an investment, and it's normal to want to be sure of what you're buying. So, treat yourself, but do so with your eyes open!
Frequently Asked Questions
How can you tell if a piece of jewelry is really made of gold in France?
To be sure a piece of jewelry is gold, look for a small hallmark. This hallmark is like a mark that indicates it's gold. In France, numbers are most commonly used to indicate the gold's purity, for example, '750' for 18 karats. If the piece is very light or very thin, it might not have a hallmark, but the seller should provide you with a document proving it's gold.
What is the difference between 'pure gold', 'gold-plated' and 'gold-gilded' gold?
When we say 'made of gold', it means the piece of jewelry is made of gold, but you should check its purity with the hallmark. 'Gold-plated' means that another metal is covered with a fairly thick layer of gold (at least 3 microns). 'Gold-gilded' is the same, but the gold layer is thinner (less than 3 microns). It's not the same quality or the same value!
Why is gold mixed with other metals in jewelry?
Pure gold is very soft and bends easily. To make jewelry stronger and more durable, it is mixed with other metals such as copper or silver. This mixture is called an alloy. It is also thanks to this alloy that different colors of gold, such as rose or white, can be obtained.
What is 'vermeil'?
Vermeil is a bit special. It's silver (which is already a precious metal) covered with a layer of gold. For a piece of jewelry to be called vermeil, it must be made of 925 silver and covered with a layer of gold at least 5 microns thick. It's a beautiful piece, but it's worth less than a piece of jewelry made entirely of gold.
Does the color of gold change its quality?
No, the color of gold is not a sign of poor quality. Pure gold is yellow, but by mixing it with other metals to make alloys, different shades can be obtained: from paler yellow to pink, red, or even white. The quality depends primarily on the amount of pure gold in the piece of jewelry, indicated by the hallmark.
Where can I find information about the purity of the gold in a piece of jewelry?
You can find information about the purity of the gold on the jewelry itself thanks to the hallmark. This small marking, often inside a ring for example, indicates the gold content in thousandths (like 750). If the piece of jewelry doesn't have a hallmark because it's too small, the seller must provide you with a certificate of authenticity or an invoice that gives this information.
