Are these prices good?

[jr]

I have 2 diamonds that I am looking at and need a little help on whether or not they are good deals. Here are the stats:
Round GIA cert. 1.38ct. 7.10-7.14x4.40mm, Depth 61.8%, Table 59%, Girdle Thin to slightly thick, faceted, Culet-none, Polish-VG, Symmetry-VG, Clarity- SI1, Color- I, Fluoresence- None
There is more info at the bottom of the report:
8759T Round AGS 0 Wt: 1.380
diam (7.14-7.19)x4.43 DV 0.7% 0
depth 61.8%
table 4.04mm 56.4% 0
crown 34.9'' 15.2% 0
pavil 41.1'' 43.4% 0
culet 0.3% V.Small
girdle 1.0Thin-2.4Sl. Thick 1.8% 0

Here''s the 2nd diamond:
Laser Insciption Registry GIA 12488853
Round
Measurements 7.20-7.27x4.60mm
Weight 1.51 carat
Depth 63.5%
Table 57%
Girdle Slightly thick to thick, faceted
Culet None
Polish- EX
Symmetry- VG
Clarity- SI1
Color- I
Fluorescence- None

My price for the 1st diamond with a simple platinum 6 prong setting and ring would be $7800 and the price for the 2ne would be $7900.
Thanks for your time.
