The Cut Grade measures how the individual proportions combine to effect the beauty of a diamond. Diamonds with a high cut grade will have a high degree of brightness, fire and sparkle. High cut grades include "Excellent" and "Very Good". Midrange includes "Good", and low end includes "Fair" and "Poor".

This grade will generally be a bit darker or lacking in sparkle.

Diamonds are graded using the colour grading scale (D-Z). Most diamonds are colourless to slightly yellow. The highest grade is "D" or colourless exceptional white +) and extends to "Z" or light yellow.
All diamonds contain imperfections. The very best, and rarest, clarity is Flawless (FL). Because many inclusions are not visible to the naked eye, diamonds are graded under 10x magnification.
