THE FOUR Cs OF A DIAMOND
 
CARAT
Diamonds are sold by the carat (ct), which is a unit of weight, not size. One carat weighs 200 milligrams, the world standard since 1914. A carat is divided into 100 points, with one point corresponding to .01 carat.
 
CLARITY
How Pure It Is
 
The clarity refers to the purity of the diamond and is based on the absence or presence of internal characteristics. Some inclusions or birthmarks can be visible to the naked eye or only noticeable under 10x magnification.
 

IF

An Internally Flawless diamond has no inclusions and very minor surface blemishes. It can be extremely difficult to locate them even at 10x magnification.

COLOR
The Depth of Color
 
Refers to the depth of color or how noticeable it is. Normal color range is colorless to varying degrees of yellow or light brown. Diamonds are graded for color by comparing them to a master scale of diamonds. The "master stones" represent the absolute least amount of color accepted for diamonds.
 

D

A Colorless (D-F) diamond is completely clear and absent of color. Not to be confused with clarity — a diamond could be a 'D' in color but could appear dark if it's heavily included.

CUT
How Much It Sparkles
 
Cut refers to the polish of a diamond coupled with balancing the proportions and symmetry to maximize light return. Even diamonds with a lower color or clarity with a supreme cut are going to have maximum sparkle to the naked eye.

DIAMOND SHAPES
Discover our selection of diamond shapes — from traditional to fancy cuts.
A timeless look and the most popular diamond shape. The round diamond represents the highest advances in diamond cutting, maximizing fire, brilliance and sparkle.
The oval cut shares the same brilliant faceting style as a round diamond. Its elongated shape has a surface area that creates the illusion of length, making it a popular cut for smaller hands.
The teardrop-shaped pear has both modern and vitage charm. Its unique cut flatters petite hands and lends a larger appearance to smaller carats.
Flattering on long hands, the emerald cut features corner facets and broad flat planes. You'll rarely see this cut in lower grades as inclusions are more obvious in this shape.
Similar to an emerald cut with the brilliance of a round diamond. The radiant cut can range from square to rectangle and is more forgiving of inclusions.
A favorite among royalty for centuries — the cushion shape varies in appearance with a square or rectangular shape and soft, rounded corners.
A graceful shape with curved sides and pointed ends. A marquise diamond can appear larger face-up while making fingers look long and slender.
This contemporary cut adapts well to a variety of settings. It has pointed corners and a modified brilliant facet arrangement that offers exceptional sparkle.
A modified round brilliant cut and the most romantic diamond shape. The cut must be exact with perfect symmetry, proportions and a well-defined outline.
An Art-Deco inspired shape often referred to as the "square emerald cut." It features a stepped square cut and cropped corners.
