Thanks for everyone who has helped so far - it looks like we're well on our way! I would really appreciate for someone to post the diamcalc or whatever program used to show a picture of light leakage, bowtie effect, etc. for the following pear:

Pear brilliant
carat: 1.01
length: 9.53
width: 6.24
depth: 2.86
depth %: 45.8%
table %: 58%
girdle: medium to thick, faceted
culet: none
polish: good
symmetry: good
clarity: VS1
color: E
fluorescence: medium blue
price: $4150

This diamond is certified by GIA, so I don't have a crown height %, etc. We are planning to purchase the diamond in a day or two - PLEASE offer any advice or concerns you may have...

Hi Blush. This diamond has a large "spread" (surface area) and VERY shallow depth (45.8%).

Being that shallow is going to cause the diamond to look "glassy" compared to one with a more traditional depth (58-65%). Reflections of the girdle should show up within the table view with a "ripple effect" just inside the edges of the table.

With a depth of 45.8%, this diamond would technically be considered as having a "fair", or possible "poor" cut. Very seldom is a diamond with this depth able to overcome that handicap and look "good". Shallow stones also tend to "dull out" when they get dirty.

The price, being unbelievably cheap for an E/VS1, is reflecting the severe influence of the cut.

Unless this diamond is breaking all the rules and looks good to you, I think I'd take a look at some other stones for comparison. Perhaps it is a "rule breaker", and you'll come back to her in the end, but it'd be nice to know that you gave yourself some choices in the process.
