The thing that intrigued me about this stone is it's seemingly perfect proportions yet less than perfect BrillianceScope results and light return.
Sarin results reveal a 71.7% depth, 66.5 table, 10.6% crown height and a 56.8% pavilion depth. All the ingredients for a superstar princess cut. Below are Diamension and Diavision
files with 3d models.
Here is the actual LightScope image of the stone.
LightScope reveals nice dark reds in the center however pale reds
and white are predominant at the top and bottom halfs of the stone.
Here are the BrillianceScope results.
Now take a look at this princess cut with similar proportions.
This is a .92ct E VVS1 we have on our site.
Sarin results on this stone reveal a 70.9% total depth %, 64.8% table, 10.5% crown height and a 57.6% pavilion depth. Very similar to the 1.04ct listed above.
Here is the Lightscope image of this .92ct.
Drastically different as we now have the presence of more dark reds and blacks
(indicative of more intense light return) and while there are some areas of leakage by the corners, leakage is reduced.
Here are the BrillianceScope results of this diamond.
2 measurements I've left out of the proportions on these 2 stones are the crown/pavilion angle combo and THIS is where the difference lies between the above 2 diamonds. A side by side comparison of the numbers reveals everything pretty similar except for one factor. The pavilion angles on the 1.04ct are shallower than the .92ct which teaches us once again the important
relationship between crown and pavilion angles even in fancies such as the princess.
