Chehua is a craft, that is, carving patterns on jewelry with professional tools and turning tools. The advantage of this process is that the pattern is vivid and beautiful, but the disadvantage is that if it needs to be refurbished, it can't be highly polished, which will affect the original pattern. Che Hua can add exquisite patterns to jewelry, making jewelry more layered and stereoscopic, bright and shiny, and the combined patterns are more tough.
There are nine kinds of jewelry made of non-ferrous metals, which are most recognized by the public: car-carving process, polishing process, sandblasting process, sanding process, wire drawing process, color wire drawing process, stamping process, wire drawing process and sand pushing process. Different crafts can show different characteristics of gold jewelry.
