Selecting a Diamond

When selecting a diamond for an engagement ring there are several criteria to consider.  These benchmarks are commonly refered to as the four C’s.  Below each are defined.  For more detailed information on each topic, click on the term.

Term Definition
Color The diamond’s color usually refers to the absence or presence of a yellow tint.  A color grade of “D” means that a diamond is colorless and a color grade of “Z” is the darkest yellow.  Diamond color progressively gets more yellow from D to Z.
Carat Weight A carat is not the physical dimensional size of the diamond but rather its weight, or more precisely its mass. 1 carat = 200 milligrams = 100 points
Cut The diamonds cut refers to the dimensions and proportions to which the diamond is cut.  Cut is critical in order to obtain maximum diamond brilliance.  Sometimes cut is often confused with or associated with style and shape.
Clarity The clarity of a diamond is the absence or presence of flaws, scratches, or mineral deposits inside the stone.  Click the clarity term to see the grading chart.


These criteria have been used for years to help customers understand the uniqueness of diamond and how that uniqueness equates to price.  Any jewelry retailer worth visiting will be able to relay details about a specific piece in their shop by using the terms listed above.

After you have determined the criteria of the diamond you want, be sure to look at the diamond’s certification to ensure those qualities.
