Although many jewelry stores can provide the service of changing rings, luxury brand rings like Cartier suggest looking for a professional and formal luxury maintenance agency to make the rings bigger. Both the maintenance technology of jewelry and the maintenance experience of technicians are relatively more mature. As a professional luxury goods repair and maintenance shop, Yujin provides customers with better services than ordinary jewelry stores, and its maintenance scope is quite extensive, including: size modification, polishing and renovation, fracture welding, deformation and plastic surgery, bruise repair, matching gems, personalized lettering and so on.
