The anatomy of a diamond plays an important role in its appearance.
The cut of a diamond determines how well a diamond is able to refract, reflect and return light. Cutting and polishing are carried out in order to demonstrate the greatest brilliance and radiance of the diamond.
The main elements forming a diamond:
1. Table
This is a large flat surface on the top of the diamond. It plays a key role in the geometry of light and the creation of brilliance.
2. Crown
The crown is the upper part of the diamond located under the platform. It consists of several facets that reflect light and create incredible lighting effects.
3. Rundist
The rundist is the middle (side) part of the diamond, located between the crown and the pavilion. It also consists of facets that reflect the luminous flux and add shine. Usually it is on it that the number of the digits indicated in the certificate for the stone is applied with a laser.
4. Pavilion
The pavilion is the lower part of the diamond, located under the girdle. It consists of several facets that reflect light and create shimmers of brilliance.
5. Kaletta
A caletta is a thorn of a stone. Depending on whether it is sharp or cut, you can judge the quality of the cut and the era. In diamonds, until the middle of the last century, the spike was most often cut off, which visually led to the appearance of a black circle in the very center of the site. Modern cutting technologies allow you to save the spike for better optics of the stones.
Other characteristics that you can find in the description of the diamond:
1. Polishing
Included in the Cut parameter. Affects the passage of rays. For diamonds smaller than 0.5 carats, polishing from bright and very uncleaned glass.
2. Symmetry
Included in the Cut parameter. Characterizes the quality of the faces and their symmetry. Affects the passage of rays inside the diamond.
3. Fluorescence
Non—fluorescent diamonds of high D - H colors have historically been more expensive in relation to their highly fluorescent counterparts. Conversely, low I— M colors with fluorescence are slightly more expensive than non-fluorescent stones, since it visually improves the color characteristics.
