It is a handy tool to identify a diamond’s qualities. Without understanding all the terms, and not being able to evaluate all the percentages, it is not that helpful for making a buying decision. It may even lead you down the wrong path. Just because a diamond has a certificate, doesn’t make it a great diamond any more than a person is considered healthy just because he/she has a medical report.

A dazzling certificate doesn’t always mean a dazzling diamond. A stone might look very good on paper but disappoint in person. Of course, every Mervis diamond is certified. But we never use a lab report alone to sell a diamond. We sit down with you and show you the diamonds, up close and personal. Diamond grading is as much of an art as it is a science.
