2. Observe the light reflection: hold the ring and compare it with the light to see if the outer ring will form a line under the light reflection. No matter how a real Cartier ring rotates, the outer ring should have a linear reflection.
3. Check the internal seal and seal cutting process: carefully observe the internal seal and seal cutting process of the ring. The internal imprint of genuine Cartier ring should be consistent with the color of the ring itself, with deep lettering and smooth lines. If it is found that the color or workmanship of the stamp does not match the original, it may be an imitation.
4. Check the overall workmanship and details: Cartier, as a world-famous brand, should have excellent workmanship quality, especially impeccable details. Authentic ring surface should be flawless and smooth. If burrs or quality problems are found, they may be imitations.
5. Check the screw position and the inner angle of the diamond inlay: observe whether the screw positions on both sides are aligned and whether the middle is flat. The inner corner of a diamond should be hexagonal, with both sides parallel to the outer side. If there is a discrepancy, it may be an imitation.
6. Check the boundary signature and independent code of 750: There should be a clear Cartier signature and six-digit independent code within the boundary of Cartier ring 750. You can check the code yourself to verify the authenticity.
7. Cleaning verification: If you already have Cartier Ring 750, you can take it to the counter or specialty store and ask for cleaning service. When cleaning, the teller may tell the truth of the ring. Or you can directly find the counter lady to verify the authenticity of the ring.
