The 4Cs

Most gemological laboratories grade diamonds based on four factors: “Clarity,” “Colour,” “Cut,” and “Carat.”

Clarity :

The clarity grade of a diamond is determined by the number and type of inclusions (characteristics) found in that diamond. There are two types of characteristics: inclusions and blemishes. Their location is what differentiates them: inclusions are found inside the diamond while blemishes form on the surface of the diamond.

These characteristics appear during its formation, and make each diamond a unique gemstone. A diamond will be better classified when, observed through a 10x magnification loupe, these characteristics are very barely visible. A diamond will be considered "internally pure" if observation through this loupe reveals no characteristics.

Color :

Many people think that diamonds are colorless. In reality, diamonds come in a wide range of hues, from colorless (D) – extremely rare – to slight tones of yellow or brown (Z).

There are also so-called fancy-colored diamonds. These are stones whose hues are not included in the standard color range. They come in every color imaginable: red, green, orange, purple, black, gray, blue, and pink. There are also the more common yellow and brown diamonds. These are classified as fancy colors when their tone exceeds category Z on the color scale.

Another element that can affect color is fluorescence. This is the visible light that diamond emits when exposed to ultraviolet (UV) light. Blue is the most common fluorescent color, but it can also be white, yellow, or orange.

This is a very complex and difficult characteristic to understand but it should not be neglected; this is why our experts and jewelers give it great importance.

Our diamonds are fluorescence free.

Size (Cut):

Cut determines how well a diamond captures and reflects light. The better the cut, the more reflection, sparkle and light it will have. It is also important to consider polish and symmetry, two attributes that are essential to the valuation of a diamond. Gemological laboratories classify these attributes on the scale of “excellent,” “very good,” “good” and “fair.”

Our diamonds do not fall below the “very good” threshold.

There are several types of cuts (brilliant, princess, oval, cushion, etc.) that each have their own particular style and interact differently with light.

Carat :

The weight of diamonds is given in a metric measurement called carat.

One carat (ct) equals 200 milligrams.

The metric carat is also divided into 100 points (abbreviated “pt”), generally used for diamonds below one carat.
