Diamond Cut
A diamonds ability to refract light and shine so intensely is one of the reasons a diamond is the gem of choice for most people. Many think about a diamond shape when referring to the diamonds cut, but a diamonds cut grade is really referring to how the light interacts with the facets on the diamond. Each diamond is cut to deliver the top return of light possible for that particular diamond.
SUPER IDEAL | Cut to the most exacting standarts. These diamonds have the most desirable dimensions and are proportioned to return the maximum possible light. Roind diamonds will show a 'hearts and arrows' facet patern. |
IDEAL | Exquisite quality cut to create the optimal combination of brilliance and fire. Reflects nearly all light that enters the diamond. Top 3% of diamond quality based on cut. |
VERY GOOD | Superior quality cut that reflects nearly as much light as the ideal cut while at a substantially lower cost. |
GOOD | Premium quality cut to optimize the size without sacraficing quality and beauty. Reflects most light that enters. |
FAIR | Adequate quality cut that reflects some light while maximizing weight. While not as brilliant as a good cut, still a quality diamond. |
Diamond Color
Despite all thoughts on diamond color referring to the amount of color seen in a diamond, it actually refers to the lack of color found in a diamond. Besides for fancy colored diamonds (pink, blue, etc.), the less yellow appearance in a stone, the more value a diamond has. The color grading starts at D (colorless) and goes down to Z (most color).

Diamond carat weight
The diamond carat weight refers to the actual weight of the diamond. For comparison, 200 milligrams equals 1 carat. Every carat can be allocated into 100 points. For example, a diamond which weighs 0.50 carats, can also be referred to a 50 point, 50 pointer diamond, or half carat diamond.
