 		Should I be concerned with these differences?

GIA CERT:
Round Brilliant
Measurements: 6.80 - 6.87 x 4.12
Weight: 1.15 carat
Depth: 60.3%
Table: 56%
Girdle: Medium, Faceted
Cutlet: None
Polish: Excellent
Symmetry: Excellent
Clarity: VS2
Color: I
Flourescence: None
Price: $5,175

SARIN REPORT:
Weight: 1.15 carat
Diam.: 6.82 (6.8-6.83)mm
Depth: 4.13mm 60.6%
Crown: 34.8 15.2%
Pavil.: 40.5 42.8%
Table: 3.82mm 56%
Cutlet: 0.6% Very Small
Girdle: 1.0% avg (0.7-1.5%)

The GIA certificate states the Depth at 60.3%, not 60.6%. Also, is a cutlet of 0.6% considered none by GIA standards?
I have read that a girdle avg. of 1.0% is considered thin, but GIA says medium, faceted. I know there are often differences in the reports, so are these differences negligible?

I would appreciate any help. Thanks.

 		It looks like whoever provided you with the Sarin results needs to calibrate their machine or clean the stone and measure it again... While the variance is subtle, it is a bit more than we would expect and it is enough to throw off the crown and pavilion angle measurements... Some variance is normal.
