Carat
Carat is a measurement of a diamond's weight. It is also a reflection of diamond size and the most visible of the 4 C's.
Cut
Cut is the diamond's shape and proportions that affect the fire, brilliance, and scintillation. Well-cut diamonds have maximum sparkle, and are also a reflection of the proper measurements for that shape and carat.
Color
Color Is a reflection of the absence of color visible within the diamond. The higher the color grade (less color), the rarer and more valuable the diamond. The scale ranges from D-Z.
Clarity
Clarity is defined by the presence of tiny attributes that occur naturally in a diamond during its growth process. They give each diamond a unique identity, and the number and placement can affect the grade.
Symmetry
Symmetry refers to the arrangement, size, and shaping of diamond facets. It's a reflection of craftsmanship, and can affect other grading criteria.
L/W Ratio
Length/Width Ratio is the diamonds proportion face up in millimeters. It is mostly relevant in fancy shapes and can tell you if the shape is longer or shorter.
Polish
Polish, like symmetry, is an element of diamond finish. It's how cleanly and perfectly the surfaces of the diamond are finished.
Table
The largest, center facet (or face) of the diamond expressed as a percentage of the length/width. It allows the most amount of light into the diamond and therefore has a significant impact on diamond sparkle.
Depth
The distance from the table to the culet expressed as a percentage of length/width. Depth has a significant impact on light leakage and performance.
Fluorescence
Fluorescence is a diamond's natural tendency to emit a soft blue glow when subjected to ultraviolet light (black light). Fluorescence can help mask lower colors but is less desirable for higher colors.
