DIAMOND CUT


While nature determines a diamond's colour, clarity, and carat weight, the hand of a master craftsman is needed to release its fire and beauty. Most of our diamonds are cut in India where DIAM Gems & Stones is also based.


Diamonds are thought to have been first recognized and mined in India where they have been known for at least 3,000 years and have been recorded in some cases almost 6,000 years ago. Nowadays, it is estimated that 92% of the world\’s diamonds still get cut in India by highly dexterous and experienced cutters.


The cut gives each diamond its unique sparkle and brilliance by allowing the maximum amount of light to enter and reflect back out of the diamond. Diamonds may be cut in different shapes: Round, Princess, Emerald, Asscher, Oval, Marquise, Heart, Pear, Cushion Diamonds are sometimes cut in shallow proportions to make a diamond look bigger but this sacrifices the brilliance and life of the diamond and makes it less valuable.





Table

This can be found on top of the diamond and is a flat facet which is the largest on a cut diamond.

Crown

This is above the girdle at the top part of the diamond. A large flat area called the table and several facets make up the crown.

Pavilion

The pavilion is the bottom part of the diamond, below the girdle.

Girdle

The circumference of the diamond that creates a band around the edge of the diamond.

Culet

This is occasionally added by cutters at the bottom of the diamond's pavilion. This tiny flat facet helps to protect the tip of the pavilion from getting chipped or damaged. Large culets were quite common in diamond's that were cut earlier in the century. Today most diamond's have either a small culet or none at all.



Facet

These are the smooth, flat faces that can be found on the surface of a diamond. The facets on a diamond allow light to both enter and reflect off its surface at different angles, which then creates the wonderful shine and dazzle that diamonds are famous for. The diagram below shows all the facets on a round brilliant cut diamond. A round brilliant diamond has 58 facets (or 57 if there is no culet).

Depth

This is considered to be the distance between the culet and the table. Depth is measured in millimeters.

Crown angle

This is the angle where a diamond's bezel facets intersect the girdle plane. A diamonds dispersion or fire is caused by this gentle slope of facets that surround the table. When white light enters at the different angles it is then split into spectral hues and this makes lots of colours within the diamond. The crown angle also assists in making the diamond appear even more brilliant.

Table percentage

This represents a comparison between the diameter of the table facet and the diameter of the entire diamond. For example where a diamond has a 60% table it also has a table which is 60% as wide as the diamond's outline. A round diamond's table percentage is calculated by dividing the diameter of the table (measured in millimeters) with the average girdle diameter. The table percentage is calculated for fancy shaped diamonds by dividing the width of the table (at the widest part of the diamond) with the width of the entire stone.
