The upper view shows a well cut diamond in profile, a diamond is nothing more than a prism it takes white light and breaks it into the spectrum.  When the cutter adheres to the proper angles in the crown (34.5 degrees) and the pavilion (40.75 degrees) with the other proportions we end up with a beautiful gem.

This Diamond Grading Report, is my own and is fashioned after the GIA report.  The information that is included in the report, if under stood by the reader gives all the necessary information that is needed to determine the 4Cs of your diamond.  The report gives the COLOR, CLARITY, SIZE or CARAT, and the CUT or PROPORTIONS.  This is all one needs to help determine value. 

Note also the diamond diagram, this is used to help identify marks and inclusions in a diamond.  This may not seem important, but when one realizes that no two diamonds have all the same characteristic's, you can see the value in having a plot of your diamond.
