The presence of brilliance, fire and scintillation is essential for a beautiful diamond therefore understanding and interpreting the finer details of cut quality and light performance will result in better choices and a brilliant, sparkling diamond. ASET goes beyond the original form of a reflector tool; it is also a theoretical basis for the American Gem Society Laboratories (AGSL) cut grading system based on light performance. The AGSL grading system is one of the most scientifically strict and technologically advanced grading systems in the world of gemmology.
