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.
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 the center.
There is a major difference between the Dolce & Gabbana and the fake here: the stamp quality. Typically, the counterfeiters make low-quality screen prints of the Dolce & Gabbana logo. The screen-print method provides no texture to the logo, whereas authentic pair of Dolce & Gabbana glasses provides a surface in the plate.
A simple check to see if you purchase fake Dolce & Gabbana 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 Dolce & Gabbana glasses, you should be able to feel the texture or some form of indentation.
The interior right arm of the D&G sunglasses has the D&G logo followed by the Made in Italy symbol and the letters CE indicating conformity with European regulations. Check for any mistakes in spacing or alignment.
New models of D&G eyeglasses often feature a metal logo at the temple's tip. The letters should look sharp and clean on the arm without signs of adhesive or gaps.
Before spending excessive money on eyeglasses, be aware that highly inexpensive glasses are often low quality. The price of authentic Dolce & Gabbana glasses is around $150 and goes up depending on the frame, lens choice, and additional features.
Each pair of Dolce & Gabbana sunglasses has a serial number etched into the right lens. Older pairs might not feature this mark. Make sure that the font and logo match the official brand identity.
7. Brand Box
The box will have the brand name printed along with high-quality printing. The package normally includes a sticker containing the bar code for the sunglasses; you can check this information to be sure you're getting legitimate D&G glasses. Guarantee cards, guidebooks, the cleaning cloth, and a pouch with a new pair of glasses are also part of this D&G purchase.
If you are choosing second-hand glasses, it's recommended to have the case and the certificate come with the glasses.
