How to Spot Fake Cartier Rings?

Cartier is a name synonymous with elegance, luxury, and timeless beauty. A Cartier ring is probably the most popular piece from the expert’s long list of jewellery collections. Whether it’s the elegant shapes, handcrafted motifs, or undeniable uniqueness, Cartier rings are the most recognisable.  

As a top luxury jewellery maker, Cartier ensures that all their items are expertly crafted and curated with high-quality materials. Unfortunately, the high demand for these exquisite pieces makes them easy targets for counterfeiters.

If you’re considering purchasing a Cartier ring, whether new or pre-owned, it’s important to ensure you’re investing in a genuine piece.

Read on as we share some insightful tips on spotting fake Cartier rings at once.

8 Ways To Identify Fake Cartier Rings

1. Examine the Stamping

All Cartier Rings have specific logos and hallmarks that are key to their authenticity. Look for the following:

  • Genuine Cartier jewellery is clearly stamped with correct spelling and even spacing. Find the stamping on the back of the rings.
  • The Cartier logo must be engraved smoothly and clearly on the ring, and the font must match Cartier’s official branding.
  • The exact stamping varies from Cartier jewellery to another. Authentic Cartier rings are stamped with their size. For example, Cartier sizes its rings in millimetres, so the ring with a size of 56mm will be stamped with 56.Moreover, Cartier engagement rings are stamped with the type of metal, the Cartier logo, and the two-digit ring size, the diamond carat weight, and the serial number. If the ring is made of 18ct gold, it is stamped with 750 or Au 750 and p50 or Pt 950 for platinum.
  • Cartier’s logo is always printed in their signature script. If you find it in any other font or misspellings, they’re indicators of a counterfeit.

2. Check the Material & Colour

Cartier uses high-quality materials like 18ct gold and platinum to make the rings, which match the stamp. It is definitely a fake if you spot any areas of discolouration, scrapes, chips or scuffs. Also, if you find a differently coloured metal beneath the top layer, it’s a sign of a fake.

3. Inspect the Craftsmanship

Cartier is renowned for its exceptional craftsmanship. A genuine Cartier ring exhibits a flawless finish with no rough edge or visible joints. The design should be perfectly symmetrical. If the ring features gemstones, they should be perfectly set onto the metal with no uneven setting or visible glue. Anything that differs from this is a red flag.

4. Verify the Serial Number

Each Cartier ring has a unique serial number engraved on the inner portion of the band. The number should be engraved clearly and not appear blurry, smudged, or stamped. You can contact Cartier or visit a Cartier boutique to verify if the serial number on the ring matches their records.

5. Look at the Cartier Box & Certificate

While the quality of the ring is an obvious thing to consider, you must also check the box for signs of authenticity. The inner boxes of genuine Cartier jewellery don’t have the famous brand logo printed on the top of the lid. Instead, the logo is printed on the top of the outer main box.

The interior of an authentic Cartier box is made of either a classic white fabric or black satin, and modern Cartier boxes are equipped with push-release buttons on the front.

The closures on the boxes also vary. Authentic Cartier boxes feature a discreet closure with no visible clasps on the top section. The fake pieces, on the other hand, have the closure system included on the top and bottom areas of the box.

Each authentic Cartier ring comes with a certificate of authenticity. Consider verifying the details on the certificate, like the serial number against the ring, to ensure it is original.

6. Feel the Weight

The counterfeiters aim to cut costs by utilising low-quality materials in smaller quantities. As a result, the fake Cartier rings will always be thinner and weigh lower. High-quality Cartier rings have a certain weight that the lower-quality rings lack. So, hold the ring and feel its weight. If it doesn’t have a considerable weight, it’s an indicator of a fake model.

7. Evaluate the Engraved Lines

This holds true for the Cartier Love rings, which also have specific design elements outside the ring. The most common characteristic is a circular shape with a line in the middle. Real Cartier Love rings are uniform, smooth, and elegant. The lines inside the circular shape are thin and do not fit too deeply onto the metal but are still very clear. On the other hand, the lines in the fake models are a tad too thick and tend to fit in the metal too deeply.

8. Too Good To Be True Prices

This doesn’t come as a surprise at all! Cartier rings are highly valued due to their brand reputation and premium-quality materials. Extremely low prices are a strong indicator of counterfeit pieces, and you must avoid them at all costs. Forgers offer lucrative deals and offers on social media platforms to entice buyers. Make sure you don’t fall into the trap.

If you’re still uncertain about the authenticity of your Cartier ring, it is best to contact professionals. An expert can often spot inconsistencies that might not be apparent to the untrained eye.
