by strmrdr » May 22, 2005 It seems like to me that when GIA and AGS set out to design a cut grading system they went about it in almost totally separate ways. GIA primarily took a look at what was available and using mainly observation research separated them into broad categories. AGS on the other hand seems to have in effect said; if we were cutting the best diamonds in the world what would they be like?, then did the scientific research to find out. Then they gave the cutters the information to cut these diamonds. Nowhere is this more apparent than the AGS princess cut grades because they found that none of the current cutting styles was good enough and took them in a new direction. With rounds it was less revolutionary because there were already cutters cutting super high performance rounds but it is none the less a huge advance in diamond cut grading. What do you think am I right or wrong in how I see it?
