The 4C’s Of Diamonds

Learn about the 4 C’s of diamonds—cut, color, clarity, and carat. Discover how each factor affects a diamond’s beauty and value with Love & Promise’s easy-to-follow guide.
Color

The more colorless the diamond is, the higher the market price.

The diamond scale ranges from D (completely colorless) to Z (the start of fancy colors). The colorless range (D-F) are the most rare and sell at a premium, especially when paired with high clarity and ideal cut. The color of the diamond will never change in any circumstance unless the colors in the stone are purposely enhanced, so there is no need to worry about the color going yellow over time.

Clarity

The number of imperfections in each stone have an impact on the value of the diamond.

Another important factor for a sparkly diamond is the clarity. We usually recommend our clients to stay I1 and higher. Typically we try to sell most of our products between SI1-SI2 in clarity. Inclusions in a stone (an inclusion is any material that is trapped inside a mineral during its formation) interfere with the light reflecting off each of the facets. For minimal eye-visible imperfections, we recommend SI1 and higher for stones that are 1 carat (ct) and over and SI2 for stones ¾ ct and under.

Cut

Angles that are cut perfectly give the diamond the most beautiful sparkle.

The cut is probably the most important aspect that determines the brilliance of the diamond. Angles that are cut perfectly give the diamond its brilliant sparkles. The cut grade scale ranges from Poor, Fair, Good, and Very Good, to Excellent.

We prefer to sell diamonds that are good cut and higher; but we highly recommend very good to excellent. A D color and VVS2 quality diamond will not sparkle if it's poorly cut. That is why we believe that having ideal to premium cut is important.

Carat

As a general rule of thumb, the larger the stone, the more expensive the stone is per carat.

The carat refers to the weight of the stone, not the measurement. Measurements for stones for length x width x depth are usually done in millimeters. All stones have different densities. For example, five different stones will appear visually different in size even though the weight will be the same because some are denser than others.
