Fair | Good | Very Good | Ideal | Signature Ideal
This diamond is cut to the finest proportions as determined by its face-up appearance, design, and craftsmanship. It reflects nearly all light as fire and brilliance as determined by the GIA. The GIA certificate lists the cut as Excellent, which is the equivalent of an AGSL or Blue Nile Ideal cut grade.
Colour: I
J | I | H | G | F | E | D
This diamond, when cut to ideal proportions, produces a warm brilliancy not found in the higher grade colours. I-colour diamonds are less expensive than other diamonds, so you can buy a larger diamond for the same price as a higher colour grade. Note: If this diamond has medium or strong blue fluorescence, its slight tint will be partially masked, making the diamond appear whiter to the eye.
Clarity: SI1
SI2 | SI1 | VS2 | VS1 | VVS2 | VVS1 | IF | FL
The inclusions in this diamond can be visible at 10x power magnification. Inclusions in diamonds with SI grade clarity might be visible to the unaided eye. SI1 grade diamonds are not as rare as VS1 and VS2 grade diamonds, so they are less expensive and present a great value.
