This diamond is cut to more exacting standards than the finest graded cuts currently available. With a Signature cut, this diamond reflects the maximum brilliance. This is our finest grade of diamond cut.
Colour: H
J | I | H | G | F | E | D
This diamond offers an exceptional balance of colour and cost in the near-colourless range. If you choose an H-colour grade diamond, you can buy a larger diamond for the same price as a higher colour grade. The very slight tint is generally not noticeable.
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.
