Trying to select diamond. Help?

Hello.

I think my brain is about to explode. I am replacing the stone in my setting that fell out - yikes.

I have a diamond on hold, but I am really nervous about making a bad choice.

Here it is:

radiant cut
cut: premium
Color H
Clarity VS2
Carat 1.26
L to W 6.26 x 5.66 x 4.35
Depth 76.9
Table 77
Girdle M-TK
Culet NON
Polish VG
Symmetry G
Flouresence NONE
$4297

the other one i was looking at: (actually there about 20!!!)
radiant cut
cut: ideal
Color H
Clarity VS2
Carat 1.21
L to W 6.98 x 5.29 x 3.81
Depth 72
Table 68
Girdle TK
Culet NON
Polish EX
Symmetry VG
Flouresence NONE
$4825

I really really appreciate the help. The diamond that I had that fell out was not certified for some reason or other, I only know that it was S11 and HI color about 1.2 it was a round.

Thanks!
Molly
