Diamond

The anatomy of a diamond 

The anatomy of a diamond consists of several key parts, each contributing to its overall shape, brilliance, and value. Here are the primary components of a diamond:

1. Table:

The largest flat surface on the top of the diamond. It allows light to enter and exit, playing a crucial role in the diamond's brilliance.

2. Crown:

The top portion of the diamond, located above the girdle and extending to the table. The crown's facets refract light, contributing to the diamond's sparkle.

3. Girdle:

The narrow band around the widest part of the diamond. It separates the crown from the pavilion and can be either polished or faceted.

4. Pavilion:

The bottom portion of the diamond, located below the girdle. The pavilion's facets reflect light back through the crown, enhancing the diamond's brilliance.

5. Culet:

The small, often pointed facet at the bottom of the pavilion. Not all diamonds have a culet; some have a pointed end instead.

6. Depth:

The height of the diamond from the table to the culet. Depth percentage is an important factor in determining a diamond's overall cut quality.

7. Crown Angle:

The angle between the girdle and the crown facets. It affects the way light is refracted within the diamond.

8. Pavilion Angle:

The angle between the girdle and the pavilion facets. It influences how light is reflected back through the crown.

9. Facet:

The flat, polished surfaces on a diamond. A standard round brilliant cut diamond has 57 or 58 facets, depending on whether there is a culet.

Understanding these parts helps in evaluating a diamond's cut, which significantly affects its brilliance, fire, and overall aesthetic appeal.
