Processing is undoubtedly a technical activity and dangerous, but if it is developed well, the raw stone bought for tens of dollars can be sold several times. Appraisal is more suitable for people with marketing mind. Generally, anyone who has a door after graduation can go to work in the Quality Supervision Bureau, or go to a gold shop to do marketing, or open a small-scale jewelry store.
