Lab Reports
The exact quality of a diamond is critical to its value. A diamond improperly graded by only the slightest margin could dramatically affect its perceived value. Often a conflict of interest may exist if someone grades the diamond who may serve to gain or lose depending upon the outcome of the examination. It is important that an independent gemological laboratory grade your diamond. Such a laboratory should be internationally recognized for the highest standards and institutional ethics. The Gemological Institute of America (GIA) and the American Gem Society (AGS) are internationally known and respected as premier research, education, and gemological grading institutes. The scientific grading reports provided by these laboratories examine the 4 C’s: Cut, Color, Clarity and Carat-Weight. These reports are recognized around the world as probably the finest opinions in existence.
