Clarity/Color 5/4.5 AGS = SI1/M GIA.

No problem. GIA's scale for color and clarity is most commonly used in the business: DEF etc for color, FL IF VVS1 VVS2 etc for clarity. AGS uses a 0-10 scale in addition (the GIA descriptors are typically included as well).

So in Clarity

AGS GIA
0 FL/IF
1 VVS1
2 VVS2
3 VS1
4 VS2
5 SI1
6 SI2
7 I1
8 I2
9 I2
10 I3

Color is treated similarly (0 D, 0.5 E, 1.0 F, 1.5 G, 2.0 H, etc.)

So on the AGS document you'll see the color and clarity expressed in both GIA terms and AGS numbers.
