In addition, jewelry is completely customized and belongs to advanced customization. This kind of customization is much more complicated, and it is completely customized according to your needs. However, rings, diamonds, precious stones and necklaces are completely customized one by one. First determine the sketch with the jeweler, and then use the drawing software to draw a sketch with accurate size through the computer to complete the preliminary design drawings. Jewelers purchase raw materials, make molds and customize jewelry according to drawings. Because it is complicated, tedious, time-consuming (some raw materials even need to be purchased abroad), it has high requirements for jewelry, the price is several times more expensive than the finished products of ordinary shops, and the customization time takes more than one month, mainly for users who require high-grade jewelry. According to the chief designer of Moonlight Box Jewelry Mall, domestic jewelry customization is basically combined customization, and few can completely customize personalized jewelry, because it requires exquisite jewelers' skills, costs, sources and other requirements. If the dissatisfaction with customization causes disputes, it will cause great losses, so few people are willing to provide this completely customized service.
