What does magnification tell me about a diamond?
Viewing a diamond under ten-power magnification will show you where the markings are. What that can tell you is whether the diamond that you are viewing is the match for the diamond that is depicted on any certificate or what the sales associate is telling you you're viewing. Viewing the diamond under the microscope can also tell you a few things, and those are really subjective, do I like the markings? Does the fact that one of the markings in there is actually garnet make me like the diamond more or make me like the diamond less? It is really an educational process that goes into the makeup of how you make a decision for the diamond. So viewing a diamond under the microscope is recommended for a variety of reasons, and your jewelry professional should be able to help you along those lines.
