What is the most worth learning in the jewelry processing industry now?

Now we talk about micro-inlaying, lifting plates and inlaying stones, and the wages in carving wax are relatively high. Micro-inlay is similar to stone-inlaying, but it is more difficult than stone-inlaying. The starting version is also called hand-made, and carving wax is also a department's type of work, but the materials are different and the technology is very similar. Friends who like making can choose these two jobs. That is, it takes more than twice as long to study than micro-inlay and stone inlay. Wax extraction is the easiest to learn, 10 days is enough! There are others that are not difficult. It will be dirty if you hit it, and there is chemical liquid in the electric gold, which is very dangerous! It shouldn't take long! Don't think hard, just choose what to do, electro-gold, wax repair, sand blasting, wax extraction, die holding! But the salary is not as high as those!
