If you want to find a job instead of doing a hobby, then first of all, you should be good at hand painting. You can start by copying some big-name jewelry styles ~ you should be able to draw three views of jewelry. Secondly, you need to know the processing technology of jewelry, such as how gems are inlaid, pointed inlay, track inlay, bag inlay and so on. . . It also includes a series of jewelry making techniques and methods such as frosting, wire drawing and filigree technology. Design should not only keep up with fashion trends, but also have its own style and concept. You can read Bazaar Jewelry magazine and learn more about some classic brands and top-notch craftsmanship in the world. If you want to make commercial jewelry, especially diamond jewelry, it is not difficult to learn jewelly CAD ~ just that jewelry design is soft. The next software, go to the book building to buy a detailed book for self-study. I think since you also study design, although it's flat, the design is all the same ~ if you want to find a job, you should prepare your own portfolio. If you just want to make your own jewelry for fun, you can actually draw your own pictures and communicate with the master of the workshop.
