The first thing to check is the overall quality of the product. Note errors in grammar and spelling, and check to see if something is printed. Also check to paint and wear. Make sure the paint is intact and not chipped.
2. Nose Piece
Next, the nose piece should have the Cartier double "C" logo.
The Cartier trademark is typically stamped on at least two temple pieces on the insides of Cartier glasses. A detail that many counterfeiters do without is that most consumers are more gravitating to the outer details and overlook the inner details. So, when you are evaluating the legitimacy of Cartier sunglasses, make sure you pay particular attention to the nose piece.
Raise your arms and make sure that the prints are centered. Many real ones can appear slightly off-center, but they should be close to center.
Next, evaluate the Cartier logo plate at the end of each arm. Following this, the "C" in Cartier must be in just the right place; up at the top.
In addition, the majority of Cartier glasses have their logo etched onto the lens. There are two major differences between the Cartier or fake here, and the quality of the stamp. Typically, the counterfeiters make low-quality screen prints of the Cartier logo. The screen-print method provides no texture to the logo, whereas authentic pair of Cartier glasses provides a texture in the plate.
A simple check that if to see if you purchase a fake Cartier glasses is by running your finger over the stamp - if you have a fake pair, you won't feel anything. On a genuine pair of Cartier glasses, you should be able to feel the texture or some form of indentation.
The majority of Cartier temples are gold and engraved by hand. In addition, these details are extremely difficult to reproduce, and most counterfeiters would prefer to avoid it.
However, some counterfeiters will attempt to reproduce it. In the event you have purchased a fake Cartier pair, check the point at which the temple is inserted and look at the spacing and centering. The Cartier temple insert ought to be centered within the tip and placed smoothly on the surface.
Before buying eyeglasses, be aware that extremely inexpensive glasses are often low quality. An authentic pair of Cartier eyeglasses with acetate rims will cost approximately $600 and a pair with platinum frames will cost approximately $3,000. If the discounted price is significantly lower than the original cost, it could be possible the glasses are fake.
Inside each pair of glasses, the Cartier signature and the corresponding serial number printed on the inside are printed on a smaller font. Seven-digit serial numbers from Cartier are provided to authenticate the Cartier glasses.
8. Warranty Card
Cartier glasses are usually sold with a leather case, cleaning cloth, and warranty card. Before purchasing a Cartier pair of glasses, be sure to request an authenticity guarantee card and warranty card. If the glasses are purchased from a private individual and do not have the included warranty card, it is still possible to find out whether a card is present.
