I think there are several requirements for jewelry appraisal:

1. Confidence and patience in jewelry appraisal theory,

The basic theoretical knowledge of jewelry appraisal is very boring, and you can't learn it without confidence and patience.

2. We must pay attention to our own research and study in the practice of jewelry appraisal.

This is very important, because the practice of jewelry appraisal is the most important!

Perseverance

Jewelry appraisal should accumulate a little knowledge, update your jewelry appraisal knowledge for a long time and keep pace with the times!

For tools, conventional laboratory instruments include: microscope, dichroic mirror, refractometer, polarizer and so on. Large-scale instruments include: infrared spectrometer, spectrophotometer, electronic probe, etc.

If you want to start your own business, you need to learn the knowledge of jewelry appraisal first, and so does your work.

Personally, there are many schools specializing in jewelry appraisal in China, but the best one is the Jewelry College of Wuhan University.
