The 4 C's of Diamonds
Cut, Color, Clarity, & Carat
The Most Important Factor in a Diamond's Sparkle
Many people assume a diamond's sparkle comes from its size, but the truth is that cut quality has the biggest impact on brilliance.
A diamond's cut refers to how well its facets interact with light. When a diamond is cut properly, light enters through the top, reflects inside the stone, and returns to your eye as beautiful sparkle.
The cut of a diamond is graded based on a scale from 'Excellent' to 'Poor', and is the most important measurement for the overall beauty of the diamond.
Even a diamond with excellent color and clarity can appear dull if it isn't cut well.
Cut
How Much Natural Color is Present Within the Stone
Most diamonds contain tiny traces of yellow or brown tones, and the color scale helps determine how noticeable those tones are.
Diamonds are graded on a scale from D to Z, with D being completely colorless and Z showing more noticeable warmth or tint.
Generally, diamonds with less visible color are rarer and can be more valuable. However, many diamonds in the near-colorless range appear beautifully white to the eye while offering a more accessible price point.
The perfect color grade depends on your personal preference, the diamond shape, and the metal you choose for your ring.
Color
Clarity
The Small Natural Characteristics That Form Inside or On the Surface of a Diamond
Clarity refers to the small natural characteristics found inside or on the surface of a diamond. These are called inclusions (internal features) and blemishes (surface features), and they are formed during the diamond’s creation process.
Diamonds are graded on a clarity scale from Flawless (FL) to Included (I) based on the number, size, and visibility of these characteristics.
A higher clarity grade does not always mean a more beautiful diamond. While clarity is important, most diamond inclusions are microscopic and cannot be seen without magnification. A diamond does not need to be flawless to be breathtaking.
Many couples choose eye-clean diamonds — diamonds that appear clear and beautiful when viewed normally — because they provide the perfect balance between beauty and value. At DaisyRae, we usually recommend VS and VVS diamonds where inclusions are not visible to the naked eye.
Round diamonds often hide inclusions well because of their brilliant sparkle.
Oval, pear, and marquise diamonds can also appear very clean due to their faceting.
Emerald and Asscher cuts have larger, open facets, meaning clarity may be more noticeable.

Carat
A Diamond’s Weight, Not its Physical Size
While carat weight is often associated with a diamond's size, it does not directly determine how large a diamond appears.
A diamond's visible size can also be influenced by its shape, cut quality, and proportions. For example, two diamonds with the same carat weight may appear different in size depending on how they are cut.
When selecting a diamond, it's important to consider how all four characteristics work together rather than focusing solely on carat weight. A well-cut diamond with balanced proportions can often appear larger and more brilliant than a heavier diamond with poor proportions.
