by neo » Dec 17, 2001 Which are the best cuts, 1A, 1B, 2A, 2B, 3A, 3B. I thought 1A was the best but on the price charts some 3A's in certain colors and clarity ranges are priced higher than there counterparts in the 1A chart. I am looking for a 3 carat diamond. On the cut grading chart it says the 53%-63% table % are weight specific in 1A, 1B, 2A grades. Do any of you know what the table % range should be for a 3 carat diamond. Thank you in advance for your help.
