The Superbuy QC team has been implementing stringent quality control measures in Dior jewelry daigou through the use of the Superbuy Spreadsheet. This tool is designed to ensure that every piece of jewelry meets the highest standards of quality and authenticity.For the Dior Rose des Vents collection necklaces, the Spreadsheet has established 20 quality inspection criteria. These include verification of the 4C grading certificates for diamonds, testing the purity of 18K gold, and assessing the sturdiness of the jewelry's setting工艺.Each piece of jewelry undergoes a meticulous quality check, and the data from these inspections are entered into the Spreadsheet's blockchain notarization system. This ensures that every detail is traceable and verifiable, providing a level of transparency and assurance to customers.Regarding the anti-counterfeiting marks on the jewelry, the Spreadsheet has developed a "Laser Engraving Recognition Module." This module uses high-definition image comparison to check the clarity and positional accuracy of the marks, ensuring that they are both clear and correctly placed.Users can view the "birth certificate" of the jewelry within the Spreadsheet, which includes a comprehensive record from the raw stones to the finished product. This feature allows customers to have full confidence in the authenticity and quality of the Dior jewelry they purchase through Superbuy.For more information and to access the Superbuy Spreadsheet, please visit https://www.superbuy.host.
