Diamond Anatomy

The "anatomy of a diamond" refers to the different parts or structural features that make up a cut and polished diamond.

Understanding these parts helps with evaluating a diamond’s proportions, brilliance, and overall appearance.

Here’s a breakdown of the key components:

Table

The large, flat top facet of the diamond. It’s the largest facet and allows light into the diamond.

Crown

The top portion of the diamond above the girdle, extending from the table to the girdle. It includes the star, bezel (or kite), and upper girdle facets.

Girdle

The thin perimeter or edge dividing the crown and pavilion. It’s where the diamond is typically held in place by a setting. It can be faceted, polished, or rough. Its also where you will find the serial number of a certified stone.

Facet

The flat surfaces on a diamond cut for light reflection and refraction. A standard round brilliant diamond typically has 57 or 58 facets.

Pavillion

The lower portion of the diamond, below the girdle, extending to the culet. It's responsible for the diamond’s sparkle by reflecting light back through the crown.
