Ask the Gemologist



Everything you wanted to know about gems but were afraid to ask.

This service is available online and covers a wide range of gem subjects, such as what is the difference between scintillation, dispersion, reflection and refraction, or is an “Ideal Cut” prettier to look at than a 60X60 diamond. What "certificates" are the best, and what do they actually tell you.

The only thing that is objective in diamond grading is the actual weight of the stone when weighed on a diamond scale; all the rest are subjective opinions based on personal examination.
