It must be Tsinghua. I majored in jewelry. In fact, it can be seen from the name of the school that this school is a strong geological major. The so-called jewelry major is famous for jewelry appraisal, not jewelry design. This is an engineering major. But it may have some lectures on jewelry design, or invite some designers to exchange experiences every year, but I think the Tsinghua Academy of Fine Arts with these lectures is not bad.

I hope it helps you.
