Hi goag,

First off this is a very hard carat/clarity/color combo to come by these days which I KNOW makes this very appealing to you.  My personal experience with diamonds of these proportions is that you will have a VERY fiery diamond in direct/strong light conditions.  I'm sure this gets an incredible HCA score with that set of angles. However when a stone like this with pavilion angles on the shallow side (when coupled with 34.5 crown angles) has shown me that when  you take a diamond like this into more suffuse light conditions the diamond will take on a darker appearance than I typically care for.   In diffuse light conditions there are 2 adverse affects that can be observed.

Diamond of the steep/deep combination generally have a glassy or watery appearance to them when observed in diffuse/office/ambient light condtions and this is reflected in HCA scores.

On the opposite end of the spectrum (shallow angles) I am finding that contrast brilliance (as observed in diffuse lights) is equally diminished and the balance of light/darks disrupted with too many darks not enough lights. 

Direct light testing is a completey different story and it should do fine in those conditions.

Hope that helps.
