Each facet of a diamond’s anatomy combines to create the sparking gem often used in wedding rings.


They’re what we think about when we think of weddings and love. After all, when a guy “pops the question,” a diamond ring is what he has in hand. There’s also that part of the wedding ceremony where rings are exchanged to signify the couple’s love for each other.

While this association may have to do with a decades-old ad campaign, it is important to know what to look for when buying a diamond.

While a diamond’s 4 C’s are important, the anatomy of a diamond is also key. If the proportions are off, this can affect the quality, brilliance, and price of a diamond.

So let’s break down the structure of a diamond: table, crown, girdle, pavilion and culet.

The Anatomy of a Diamond

Table: The table is the top surface and is the one we see the most of. This is the flat portion you see when you look down in this clear gem.

Crown: The crown is the next most visible portion of a diamond.This is the narrow area right under the table, and is prone to scratching as a result of typically sitting right in the groves of the prongs of a setting.

Girdle: The next part of the diamond is the girdle. It sits right under the crown and is the widest portion. However, too narrow of a girdle subtracts from a diamond’s strength, and too broad of one adds unnecessary weight. Either one can take away from the gem’s brilliance.

Pavilion: This is the longest part of the diamond. The pavilion is angled and allows light to enter the jewel from a different facet.

Culet: Lastly, the culet is at the very bottom of the diamond. This tip finishes off the gem and gives it a symmetrical look. The culet may vary depending on the cut of the diamond and may have varying degrees of quality.
