It is useless to learn jewelry appraisal without practical experience. It is more difficult to learn to carve wax. An apprentice with almost no income has been alone for a long time. It is easy to cut and polish stones, but the labor is quite low and can only be learned in factories. Jewelry design is good, but it needs more time, because you need to see more to feel it unless you are a design genius. In a word, when the jewelry industry first enters the business, it always has to pay, and we can't talk about returns, because experience and time are very important in this industry, and there is no shortcut.
