Diamond Guide

Buying a diamond is a very personal experience. Diamonds are bought to signify love, accomplishments, and milestones in a person's life. Unlike when you buy clothing, electronics, or cars, the features of a diamond may not seem quite as obvious to you. We would like to change that. The more you know about your diamond jewelry, the more confident you will feel when making your diamond jewelry choices. The Four Cs play an important role in determining a diamond's value and making your diamond unique. 




The shape is the stylistic outline of a cut diamond and is often confused with the cut itself. Choose a shape that you like based on your style, and you cannot go wrong. 





The cut of a diamond determines its brilliance or sparkle. Before a diamond is cut, the location of inclusions and flaws, the natural coloration, and the original shape of the rough stone are studied extensively. The stone facets are then mapped out and cut in a way that maximizes size, shape, and clarity.

Most shapes have a standard brilliant cut consisting of 57 or 58 facets that reflect light in every direction. Other shapes (emerald, asscher, and baguette) have step cuts. Prior to the advancement of diamond cutting technology, diamonds had less brilliant cuts such as the rose cut and the old mine cut, which are used less frequently today.

For optimal light performance, you want a symmetrical diamond with a pavilion that is cut neither too shallow nor too deep. A shallow cut sends more light out the bottom, while a deep cut sends more light out the sides. A very skilled cut alone can give you the benefits of the other three Cs.

Diamond Cuts



Diamonds are graded on the amount of color they possess. The normal color range scale runs from D (colorless) to Z (light yellow). An absolutely colorless diamond is rare and therefore very valuable. Color becomes much harder to detect once a stone is set in a ring and is reflecting the colorful environment around it.

There are also colored diamonds outside of the normal range known as fancy color diamonds. They can be either natural or treated, and the rarest and most valuable natural colors are saturated pinks, purples, blues, and greens. They are graded on their color saturation and distribution. 

Diamond Color Scale



A diamond is distinguished by its natural characteristics present on its surface (blemishes) or within the stone (inclusions). The clarity is judged by the number, size, and types of these features and is designated using a scale that runs from Fl, defined as flawless, to I3, defined as inclusions visible with the naked eye. A flawless diamond is rare, comprising .001% of world diamond production.


  • Flawless (FL) - No inclusions or blemishes are visible to a skilled grader using 10× magnification
  • Internally Flawless (IF) - No inclusions and only blemishes are visible to a skilled grader using 10× magnification
  • Very, Very Slightly Included (VVS1 and VVS2) - Inclusions are difficult for a skilled grader to see under 10× magnification
  • Very Slightly Included (VS1 and VS2) - Inclusions are minor and range from difficult to somewhat easy for a skilled grader to see under 10x magnification
  • Slightly Included (SI1 and SI2) - Inclusions are noticeable to a skilled grader under 10x magnification
  • Included (I1, I2, and I3) - Inclusions are obvious under 10× magnification and may be visible to the naked eye. May affect brilliance and durability.



Carat Weight

The unit of measure used for the weight of a diamond is the carat. One carat is equivalent to 200 milligrams. The carat weight affects the overall size of the diamond; however, the dimensions (described in millimeters) will fluctuate among different diamond shapes of the same carat weight.

When comparing two diamonds, please note that just because one is twice the carat weight of another does not mean that it will appear to be twice the size. Additionally, a larger carat diamond with a poor cut can appear smaller than a lesser carat diamond with a better cut.
