Anatomy Of A Diamond

While each diamond is unique, certain structural characteristics are shared by all diamonds. The anatomy, or basic structure, of a diamond determines its proportions, brilliance, dispersion, and scintillation. Each component of a diamond has a specific name, and understanding how each component contributes to the diamond as a whole will help you find your perfect diamond.

Principal Parts Of A Diamond

There are 5 main components of a diamond. They are referred to as; the Table, Crown, Girdle, Pavilion, and Culet, respectively. Buyers must be knowledgeable about each aspect that contributes to an ideal cut diamond. Even the slightest variation can lead to purchasing a diamond that lacks brilliance, appears dull, or is priced above its value due to one component being cut incorrectly, such as being too thick. Understanding these factors is crucial in ensuring you select a diamond that truly shines and offers excellent value for your investment.

Table Of A Diamond

It resembles a tabletop and has a flat surface area. This makes it the largest facet on your diamond as its the top section of your jewel. The table is an essential part of your diamond, as light enters and exits through the table, determining its brilliance. Too large and the upper facets of the crown won’t have room to refract, too small and very little light can get in.

Crown Of A Diamond

If you were to view a diamond from the side, you could make out the various types of facets that comprise the crown. It is also the layer between the table and girdle. Due to its visibility, it is also the most likely area to get scratches. In almost every setting the crown sits right above the prongs that hold the jewel in place. In addition, the Crown is crucial in letting light into the diamond and has direct relation to a diamond’s Table.

Girdle Of A Diamond

It is the narrow rim around the widest part of a diamond. This section is the intersection of the pavilion (bottom portion of the diamond) which defines the circumference of a diamond. It is also referred to as the setting edge because the girdle is where a diamond is held when set in jewelry. The Girdle is also the area where the majority of the diamond’s weight reside, which allows cutters to “hide” weight and maximize yield from the raw diamond material.

Pavilion Of A Diamond

The bottom portion of a diamond, extending from the girdle to the culet. The pavilion bridges the girdle and the culet (point) and form at the bottom (culet). The pavilion is essential to a diamonds refraction (reflection is what every diamond does but refraction indicated light entering the diamond and existing is array of colors). It’s angle is crucial for refraction of light.

Culet Of A Diamond

The facet at the tip of a gemstone. The preferred culet is not visible with the unaided eye (graded “none” or “small”). This small facet was originally intended to protect the diamond’s pavilion, although today’s settings are usually strong enough and makes this feature unnecessary.

Depth Of A Diamond

When viewed from the side, a diamond’s depth is the distance from culet to the top of the table. Basically depth % refers to the height of a diamond. Depth is measured in millimeters and percentage. The depth % of a diamond can be achieved by dividing the depth by the width. The ratios and sizes of a diamond’s depth is one of the main factors impacting diamond cut quality.
