Cut
​
A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut does not refer to shape (pear, oval), but the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly impacts a diamond's brilliance; this means if it is cut poorly, it will be less luminous.
The most popular of diamond cuts is the modern round brilliant, whose facet arrangements and proportions have been perfected by both mathematical and empirical analysis.

Colour
​
Diamonds occur in a variety of colors — steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black. Pure diamonds are perfectly transparent and colorless. Diamonds are scientifically classed into two main types and several sub-types, according to the nature of impurities present and how these impurities affect light absorption

Clarity
​
Diamond clarity is a quality of diamonds relating to the existence and visual appearance of internal characteristics of a diamond called inclusions, and surface defects called blemishes. Clarity is one of the four Cs of diamond grading. Inclusions may be crystals of a foreign material, or structural imperfections such as tiny cracks that can appear whitish or cloudy. A clarity grade is assigned based on the overall appearance of the stone.
Diamonds with higher clarity grades are more valued, with the exceedingly rare Flawless graded diamond fetching the highest price.
