Heather, a graduate gemologist at Gotthelf's My Jeweler, demonstrated the masters set of diamonds there. Clarity and certificate go together because a trained gemologist can use a microscope to map a diamond and use a diamond grading report to detail all of the characteristics of your diamond. Many of the diamonds in Vail are already certified. With proper papers you know exactly what you are purchasing, if you know what the information guarantees. Clarity, for instance, is designated on a certificate.
Few diamonds mined are in the flawless grade.
Inclusions, those characteristics that penetrate the stone, and blemishes, confined to the outside surface, are two main criteria used to determine the clarity grade. No two diamonds, even of equal clarity grade, are alike. Once again the system is worldwide and accessable. Ranging from Flawless to imperfect there are three grades in between, with a first and second degree of imperfection in each. VVS1 and VVS2 are simply very very slightly included.
