I'm in this business ~Autocad has nothing to do with jewelry design. Jewelcad is a modeling software, made in Hong Kong, not bad! However, the general jewelry design of the company needs strong hand-drawing ability. Hand-drawing is the first in software operation, and it is useless to learn it. To be a jewelry designer, you have to have strong hand-drawing ability and painting ability, and you also need to color. But I advise you, you don't need to enter this industry, which is not as good as you think. Only 5000 ~ 6000 designers are awesome. Unless they are famous and have experts to take you, it's almost the same. You might as well be a good graphic designer, so you can find a job and get a good salary!
