So then if HCA =1 for the diamond above than that would be excellent, no?
note - with crown and pavilion angles at the shallower ends ( CA 34- PA 40.6) and steeper ( CA 35- PA 41) check to make sure these angles complement in that particular diamond - eyeballs, Idealscope, trusted vendor input - check as appropriate!
With that said, here''s a "Cliff''s Notes" for staying near Tolkowsky/ideal angles with GIA reports (their numbers are rounded): A crown angle of 34.0, 34.5 or 35.0 is usually safe with a 40.8 pavilion angle. If pavilion angle = 40.6 lean toward a 34.5-35.0 crown. If pavilion angle = 41 lean toward a 34.0-34.5 crown.
GIA "EX" in cut is great at its heart, but it ranges a bit wider than some people prefer, particularly in deep combinations (pavilion > 41 with crown > 35).

The stone has a cut-grade by GIA: Very Good
The vendor lists the cut-grade as Ideal.
No, as outlined by my fellow posters. Along with the score, look at where the x falls, it''s out in no mans land. Ideally it should fall in the overlap area of the GIA/AGS boxes, or at least in GIA territory/close to.Date: 2/24/2009 8:34:45 PM

The pavilion angle is like an engine within the diamond which helps dictate light return along with a harmonizing crown angle preferably. However it is important to view the diamond as a whole rather than one specific part, the overall proportions and finish work together to make the diamond come alive and sparkle.Date: 2/25/2009 10:47:38 AM

What exactly does the pavillion angle do? Sorry for all the questions....
Is it possible to find a 2 ct. stone G-H SI1-SI2 for around 12,000 -13,000 or is that a shot in the dark?
No need to overcomplicate things, I know it seems like a lot to take in and it is, but if you work with a vendor who has GIA Excellent and AGS0 hand picked diamonds, then they will be able to advise you and work with you to get you a beautiful rock, so thats the cut stuff taken care of. Also you can always run any diamond you like by the vet PSers who will help as you have done.Date: 2/25/2009 11:23:11 AM
