Investing your money into a diamond is a big step. There is so much to know and learn about diamonds to make sure you’re getting the best quality and the right look that you desire. Some diamonds are cut to sparkle, whereas others are cut to shine. If you're after a diamond with both these characteristics, then look no further than the round brilliant cut diamond!
There are 4 main components that when put together, determine the beauty that your diamond has. These are more commonly known as the 4C’s and stand for:
We have lots of content on the 4 C’s which will help you fully understand how they all contribute to the diamonds overall flair. For more info please see our blogs on:
So, what is special about a round brilliant cut diamond?
A round brilliant cut diamond gives off the best fire (the rainbow colour that can be seen when light hits it) this is because it is cut in a particular way to show its full potential.
The diamond benefits from being cut to certain proportions, to allow the light that hits the diamond to reflect across and back out. If the diamond is not the perfect cut, light coming in can be lost, dulling the sparkle.When a stone is cut to ideal diamond proportions, light entering from any direction is fully reflected through the top of the diamond and dispersed into a sparkling and brilliant display.
The diamond is cut to create 57 (sometimes 58) perfectly symmetrical facets, which act almost like mirrors, reflecting the light across and out the top of the diamond. The facets are the polished edges that are created after a diamond has been cut.
The diamond cut sections
the crown and the pavilion
The Crown is made up of 33 facets. This includes:
- 1 table
- 8 star facets
- 8 main (kite) facets
- 16 upper girdle facets
The pavilion is made up of:
- 8 pavilion main facets
- 16 lower girdle facets
Sometimes, a culet facet can be added, which is situated at the bottom of the diamond where it makes a point.
A culet is more commonly used in old European cuts and old mine cuts over a century ago. They aren’t as popular nowadays as the larger the culet facet, the more visible it can be through the table facet (the smooth top one).
This makes the total number of facets in the pavilion either 24 or 25. Having the full 57 facets allows the light to be picked up from any angle, without having to polish too much of the diamond away, whilst keeping a good carat weight.
The size of the girdle on your diamond also determines how good of a cut it is. This is the middle section of the diamond, separating the crown and the pavilion. The girdles thickness is very important as if it is too thin, it can cause damage to the stone. If it is too thick, it can increase the depth of the diamond, resulting in the pavilion becoming too deep, resulting in a poorer cut.
There are many modifications of the brilliant cut itself, including the oval, pear, marquise, heart shaped and princess cut. These are more commonly known as a fancy cut. The facet sizes and amounts vary with these styles, but they still give off that bright sparkle when the light hits it.
The diamond itself
If your diamond is certificated, then you will have a full graded report on your diamond. This includes the colour, clarity grade (including a full mapped out picture of the natural inclusions within the stone) and your carat weight.
There are also grades for the cut, polish and symmetry. The angle of every facet has been precisely calculated to reflect the light, creating a stunning, scintillating display from even the smallest amount of movement.
