How To Spot A Real Cartier: Your Ultimate Guide to Authentic Cartier Jewelry

Since its establishment in 1847, Cartier has been synonymous with unparalleled elegance and luxurious craftsmanship. Over the years, Cartier has adorned royalty and celebrities alike, cementing its status as a symbol of opulence and sophistication. However, with the rise of counterfeit luxury jewelry, distinguishing between genuine Cartier pieces and imitations has become more crucial than ever.

Here is your comprehensive guide on how to spot a real Cartier necklace or bracelet, ensuring that your precious jewelry investment is indeed an authentic piece from this iconic brand.

1. Check that Autograph
One of the most telltale signs of a genuine Cartier piece is the signature. Cartier's signature is consistently straight, with no crookedness. Pay close attention to the alignment of the letters and ensure that the connection between the 'i' and 'e' is perfect. Counterfeit pieces often exhibit uneven signatures and thicker fonts, giving away their inauthenticity.

2. Serial Numbers Are There For A Reason
Authentic Cartier jewelry comes with a unique serial number that is meticulously engraved. Counterfeit pieces may have missing or misplaced serial numbers, uneven spacing, or a different sequence altogether. Familiarize yourself with the accepted serial number formats: 5 digits and one letter (e.g., 12345 A), 2 letters and 4 digits (e.g., AA 1234), and 3 letters and 3 digits (e.g., ABC 123).

3. Weigh It Up
The weight of Cartier jewelry is a significant indicator of authenticity. Cartier exclusively uses 18 karat gold or platinum in their pieces. Counterfeit pieces often use cheaper metals, resulting in a noticeable difference in weight. While weight alone may not be foolproof, it remains a valuable factor to consider.

4. Diamonds Are A Girl’s Best Friend
Cartier's expertise in diamond setting is unparalleled. Genuine Cartier diamonds are seamlessly set, creating a floating effect. Counterfeit pieces may have diamonds set in a more metallic appearance, with uneven and sloppy workmanship. The quality and precision of diamond setting are crucial aspects to scrutinize.

5. Know Your Stuff
Familiarize yourself with the evolution of Cartier's signature over the years. Cartier has made distinct adjustments to its signature from the 60s to the present day. Older pieces may have variations that could be mistaken for counterfeits if not considered in the context of Cartier's historical changes.

In conclusion, Cartier's jewelry is a timeless investment, and knowing how to identify authentic pieces is essential for any collector or enthusiast. Whether you are purchasing a vintage piece from a few years ago or several decades ago, your knowledge and attention to detail will ensure that you acquire a genuine Cartier treasure.

    I have a cartier love bangle.18ct yellow gold, 4 diamonds, serial number ASN 583. how do I check its authenticity please? It weighs 27.5 gms, which I think is underweight.. my daughter has the same bangle, one size down, hers is a 17, mine an 18, and hers weighs 31 gms. Hers was from a cartier boutique, mine was not. I’ve noticed the cartier weight chart seems a little generous for reality!
