In fact, according to my experience, NGTC's diamond grading certificate is more useful, and I can learn some basic knowledge of diamond grading through training. The accumulation of actual appraisal experience still depends on seeing more diamonds. Other certificates are useless if you take too many exams.

Certificates of jewelry appraisers and registered appraisers like that are difficult to test, and generally you need to have some relevant work experience. Otherwise, it will be difficult for you to pass the exam.

In short, if you want to work in the jewelry industry now, people value experience more than a paper certificate.
