While you''re on the topic of pavilion angles...

I''ve been watching these forums while searching for a diamond and all the talk about PAs reminded me of a diamond I came across that I wasn''t sure what to make of. It''s graded GIA excellent with a 40.6/36.5 combination (62.4 depth, 56 table, 80 LGF, 50 star if I remember right). I didn''t see the stone in person and don''t have access to the ideal scope images. Any thoughts on what a stone like that would look like?

A combo like that would tend to be very fiery, if it has decent optical symmetry could be a very nice stone.
40.6 balances with a 36.5 well and the 80% lgf is where it needs to be for the combo.

The stone was graded excellent for polish and symmetry. What kind of leakage would you expect and would it look decent in lighting conditions that are more suited to showing off brilliance than fire?

leakage wont be a big issue if its has decent symmetry and reasonable tightness.
obstruction is an issue but the balanced c/p angle and longer lgf% help with that.

There are brighter combos but they would have less fire.
Its all in what you want brightness,balance, or fire
Pick one....
