To buy or not to buy?

[PearCraze]

I need your help..... I am in the middle of purchasing a 1.82 carat pear cut diamond online, they sent me the following pictures and a very short video (which I haven't figured out how to post yet). My concern is that the diamond looks a little dark. The video and other pictures have the look and brightness of the first picture below even when rotated. I would expect more areas of white reflections for an excellent cut diamond. The zoomed in picture shown has a very large "bright area" across the belly but this was from the original diamond supplier. I am not seeing that brightness in the other pics which were taken by the vendor who received the diamond. Any thoughts?

GIA Specs:
carat: 1.82
width/length/depth: 6.98 x 10.22x4.40mm
l:w= 1.47
color/clarity: D/VVS2
Polish/Symmetry: Both Excellent
Fluorescence: Medium Blue
57% table, 63.5% depth






Thanks!!!!
