I'm a jewelry designer, I think so. To learn jewelry design, you don't have to learn painting first, then learn professional knowledge. But a certain foundation of art painting is essential and very important.

If you have no foundation at all, I suggest you learn basic painting knowledge.

If you have a little foundation, even if it is not much, you can choose to start studying majors first, but it is also a wise choice to learn the basics of art first.

From the work point of view, if you do the design of hand-drawn drawings, it is strongly recommended to learn painting well first. At least sketch should be learned.

If it's a starter version, you don't have to learn to draw in this respect. It is enough to learn how to do it from the master.
