Diamond Certification

Video Transcript

"In this section we will talk about diamond reports or appraisals that are issued with colored stones or diamonds. These reports are issued by known laboratories throughout the world be them from the United States which our most important laboratory is the GIA the Gemological Institute of America and in Europe it is the European Gemological Laboratory and probably the two most important appraisal firms in the world. Others exist but we just only are talking about these two at the moment. This particular report as all others do identify a stone to its very close fingerprint. It will identify the weight of the stone as in karats and it further identifies it by its millimeter sizes by its depth, its height and its roundness. You can also break those parameters down into percentages of what the facets, the girdles, the table, the pavilion, you have all of these things that make this stone do what its doing and there are parameters that stand for ideal and then there are some that stand for less. Then you go into finishes as to how someone took the care or not the care to polish the stone and that is given in very good fair medium. Also the reflective surfaces are very important. The culet meaning is a point to the very bottom. Some, especially in Europe, some polishers will bob the culet to keep it from chipping because a diamond has plain and it will splinter like a piece of wood. Further you go into the grade and clarity. A grade clarify will be measured by those inclusions in which we earlier talked about and the size of those inclusions and how many. The next issue is about color grading where we use a standard grading set of stones to judge the color of this before we assert a classification. All of this is signed by a person within the industry with whom has credentials to support these appraisals."
