by bmac » Feb 15, 2002 Do the L/W dimensions add/take away from the brilliance/fire/etc of a diamond. AGA says it should be in the range of 1.33-1.66: 1. So I guess what I'm asking is that if you had two oval diamonds identical in every aspect except that one was longer and narrower (ie. 9.61/6 = 1.60) and the other was squatier (ie. 9.12/6.16 = 1.4, which one would be preferred. Does one or the other cut tend to more light?
