The Superbuy QC team has implemented stringent quality control measures in the Dior jewelry daigou process through the use of the Superbuy Spreadsheet. This tool is designed to ensure that every piece of jewelry meets the highest standards before it reaches the customer.For the Dior Rose des Vents series necklaces, the Spreadsheet has established 20 quality inspection criteria. These include verification of the 4C grading certificate 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 customers with confidence in the authenticity and quality of their purchase.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 meet the brand's standards.Users can view the "birth certificate" of their jewelry within the Spreadsheet, which includes a comprehensive record from the raw materials to the finished product. This transparency allows customers to see the entire journey their jewelry has taken, from the sourcing of the stones to the final craftsmanship.For more information and to access the Superbuy Spreadsheet, please visit Superbuy's official website.
