Understanding the 4 Cs
The 4Cs stand for cut, color, clarity, and carat.
They are considered the international standard of measuring a diamond’s value. Each C has a specific way of being measured and graded; their quality is recorded in a diamond grading report.
The first C is cut. The most important thing to remember about a diamond’s cut is that it is not the same thing as its shape. A diamond’s cut refers to its facets.
When a diamond’s proportions are cut to exacting precisions, light enters and exits the diamond through its “table”. Each cut is evaluated on the diamond’s “face-up” appearance, and its balance of proportions, durability, polish, and symmetry.
The lab-grown diamonds used in our sustainable collection all boast “ideal” or “excellent” cuts.
The second most important of the 4Cs, color, actually refers to the absence of color in a diamond. Diamonds come in a variety of hues, but truly colorless white diamonds are rare, as most have a slight hint of yellow. The closer to colorless a white diamond is, the rarer and more valuable it becomes.
Starting from D, meaning absolutely colorless, the scale follows the alphabet downward. Colorless to near colorless diamonds appear clear on the scale, and sit in a range of D through J. Anything beyond J is where slight amounts of pale yellow begin to show through.
Our sustainable collection uses exclusively D-colored diamonds - the whitest possible.
A diamond’s clarity refers to the visual purity of the rock. It is determined by the number of imperfections or inclusions in the stone and can be difficult to see without the help of a magnifier.
These inclusions occur naturally during the growth process (wether in a lab or under ground) and are what make each diamond unique. These imperfections can affect how light passes through the stone, obstructing the refraction and return of light. This can impact how “cloudy” a diamond appears.
Five factors are considered when assigning a diamond’s clarity grade. The size and number of imperfections, their position within the rock, how they impact its durability, and the noticeable contrast between the imperfections and the diamond itself.
Our sustainable diamonds are extremely pure - we only offer high clarity grades (VS1 and above) that are without any eye-visible inclusions to deliver maximum brilliance.
A diamond’s carat refers to its weight, not size. A diamond carat is equal to 0.2 grams. If carat is the most well-known of the “C’s,” it is because it can look different from diamond to diamond and shape to shape.
When it comes to carat weight, bigger is great (we love a big rock) but it isn’t always better. The cut can influence how large a gem appears. In fact, a higher carat diamond with a poor cut can appear smaller than a lower carat diamond with an excellent cut.
