The Guide to Gold Hallmarks in France: How to Recognize 18k and 9k Gold

In the world of precious metals, a tiny symbol makes all the difference. Discreetly engraved on a piece of jewelry, the hallmark is the official state guarantee, the signature that certifies the purity of the gold you hold in your hands. But do you know how to recognize it?

At La Fille du Sud, transparency and quality are at the heart of our business. That's why we offer you this comprehensive guide to help you decipher these hidden brands and become a savvy shopper and designer.


What is a Hallmark?

In France, any gold item weighing more than 3 grams must bear a hallmark issued by a customs office or by the manufacturer (if they have a delegation agreement). This hallmark certifies the "fineness" of the gold, that is, its concentration of pure gold in the alloy.


The 18-Carat Gold Hallmark (750/1000): The Eagle's Head

It is the most famous hallmark in French jewelry.

  • The Symbol: An eagle's head. For new books, it is inscribed in a hexagon.

  • What it means: This piece of jewelry is made of 75% pure gold . This is the standard for fine jewelry, guaranteeing a rich color and great preciousness.

  • Our Commitment: All our supplies in 18-carat gold are guaranteed under title 750/1000.


The 9-Carat Gold Hallmark (375/1000): The Clover

It is the hallmark that guarantees access to genuine gold.

Where to find the hallmark on a piece of jewelry?

The hallmark is always placed in a discreet location so as not to detract from the aesthetics of the piece of jewelry. Look for it with a magnifying glass:

  • On a ring: Outside the ring, at the bottom.

  • On a necklace or bracelet: On the end ring, just before the clasp.

  • On a pendant: On the bail (the ring that connects the pendant to the chain).

  • On a clasp: On the body of the clasp itself.

Conclusion: Trust as the Most Beautiful Jewel

Knowing how to recognize a hallmark gives you the power to verify the quality and authenticity of a gold jewel. This fundamental knowledge protects you and enhances your work as a designer. By choosing a trusted French supplier like La Fille du Sud, you can be confident that every piece you purchase meets these standards of excellence.
