This diamond has been cut to allow it to reflect nearly all light as fire and brilliance, as determined by the GIA. This is an outstanding cut with a negligible visible difference from an ideal-cut diamond, but at a lower price.
Color: E
J | I | H | G | F | E | D
An E-color diamond is colorless to the unaided eye. Only a trained gemologist using special equipment can determine any color difference between a D- and an E-color diamond.
Clarity: SI2
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. SI2 grade diamonds are not as rare as SI1 and VS2 grade diamonds, so they are less expensive and present a great value.
