Our Color and Clarity Grading Standards
Precise means that we follow the GIA guidelines to the letter.
Simple means we have only two colors and three clarities.
The colors are white (G - I) and extra white (D - G)
The clarities are:
Cleanish (Vs1+) eye clean (SI1) and piqué (I1)
Uniform means that less than 1% of the stones in a parcel have a lower color or clarity than the rest of the parcel.
