There are a few distinct benefits of acquiring further training in the areas of appraisal theory, ethics and methodology. First, by acquiring additional training, the gemologist will become more reputable as a whole. Individuals who entrust their gems and jewelry to one in this field often find that a more educated individual is likely to have more expertise in the area. By having such additional education, the gemologist is holding himself/herself out to the public as being more knowledgeable in this field.

Another benefit to gaining further training in the various theories of appraisal, ethics and methodology is that it gives the gemologist a better understanding of what they do on a daily basis. Not only will they know how to evaluate the gems and jewelry but they will then know how to valuate such items. Gaining knowledge in these areas will make the gemologist more well rounded and often better equipped to do their job.
