To learn jewelry design, you don't have to go to a school to receive academic education, unless you want to get a diploma or degree certificate from a school. If this is the case, adult education can be considered. I don't know much about this adult education, but schools in this field can tell you for some reference.

1. China Geo University (Wuhan) 2 1 1 Maybe this one can't get in. Adult education should not enroll students now.

2. China Geo University (Beijing) 2 1 1 also has a major in design, but I don't know whether or not to enroll in adult education, maybe not.

3. There are three schools in Wuhan Jiangcheng College of China Geo University, which specialize in design. It is not clear whether they are adults. Some of them are more likely.

4. Panyu Vocational and Technical College is located in Guangzhou and has jewelry design.

5. Shanghai Jianqiao College has jewelry, which is said to be an order-based education. I don't know how.

According to your situation, the latter two should be more reliable.

If you just want to find a job related to jewelry design, and you prefer painting, then I suggest you just take some jewelry design training courses directly, so that you can get started quickly.

For example, the jewelry design training course of Dada (Wuhan) Jewelry can be found on the website of Dada Jewelry College.
