Chanel authenticity card: irrefutable proof of a new piece of jewelry
Are you planning to buy a new piece of jewelry? If so, it's very easy to ensure you're buying an authentic Chanel piece . Each product comes with a Chanel certificate of authenticity . That said, a certificate of authenticity can also be counterfeit! To be absolutely sure you're not being scammed, simply buy directly from the Chanel brand or through an authorized Chanel retailer .
Genuine pre-owned Chanel jewelry: how to tell if it's authentic?
When buying a pre-owned Chanel piece , it's more difficult to be sure it's authentic. However, here are a few things that can help you distinguish the real thing from a fake .
The Chanel hallmark
All luxury jewelry is hallmarked. A hallmark is a type of engraving that discreetly marks a piece of jewelry. It indicates the precious metal content of a piece, as well as its origin . If a piece of Chanel jewelry lacks a hallmark , it is undoubtedly a counterfeit. The alignment of the letters must be precise, and the font must be consistent. Look for spelling mistakes or inconsistencies in the hallmark, as these can sometimes reveal that it is a fake Chanel piece .

Certificate of authenticity for a Chanel jewel
A piece of jewelry accompanied by its Chanel certificate of authenticity is more credible. It will include the jewelry's serial number , if not already present on the piece itself. This number allows for essential checks to ensure the legitimacy of the origin and the authenticity of the product . This is precisely the subject of our next point! Because, after all, even a certificate of authenticity can be a fake.
Chanel serial number to authenticate a pre-owned piece of jewelry
Every recent Chanel bracelet, ring, or necklace comes with a serial number. Look for this Chanel serial number on the piece of jewelry and verify its authenticity with Chanel if you have any doubts.
At Miller, we systematically perform this work during the authentication process for the jewelry we are about to display. Furthermore, Chanel maintains a database of stolen jewelry. This verification also ensures that you won't end up buying a Chanel piece that has been stolen from its owner.
Chanel luxury box
Authentic Chanel jewelry comes in high-quality packaging. Check the quality of the box; genuine Chanel items often come in a black box with the Chanel logo in white or gray.
Intrinsic quality of pre-owned Chanel jewelry
Chanel is a luxury jewelry brand . Therefore, it doesn't sell pieces with shoddy workmanship. If the craftsmanship on a Chanel ring, necklace, or bracelet is clearly imprecise, it's a poor imitation.
Tips to ensure you buy an authentic pre-owned Chanel piece of jewelry
The best way to ensure the authenticity of a pre-owned Chanel piece is to buy from a trusted, specialized jeweler, such as Miller Paris , which certifies all its vintage and pre-owned jewelry .
