The fashioning of natural coloured diamonds into its final shape is a complex subject that requires years of expertise.
Unlike colourless diamonds where the objective is to have the diamond show as little amount of yellow or brown as can be possible, the objective of fancy colour diamond cuts is to allow the inherent colour to come forth as strong as is possible.
The knowledge to accomplish this objective takes years of experience. LadyLux Diamonds has been involved with diamond cutters for over a decade, experimenting and honing the techniques of cutting parameters that bring forth the diamonds body colour to its fullest strength.
When a diamond is in the process of fashioning there are many factors that can affect the finished dimensions of round and fancy shaped diamonds. This is especially true for fancy shapes.
These factors include:
- Girdle thickness
- Crown or pavilion height or depth
- Enhancement of fancy colour
- Removing unsightly flaws
- Personal shape preference
With that said most fancy colour diamonds are fashioned in what is known as fancy shapes. It is rare for a fancy colour diamond to be fashioned as a round brilliant cut diamond due to the fact that diamonds of this shape tend to hide colour.
It is also rare for diamonds larger then 10 carats to be fashioned as a round diamond regardless of the presence or lack of colour.
The majority of the diamonds that are represented by LadyLux Diamonds are fancy shaped diamonds. Of the group of fancy shapes the majority are fashioned into what is known as a Radiant cut.
This is a trade name for a diamond that GIA will call a cut-cornered rectangular modified brilliant. There are many different styles of facet arrangements as well as the length to width ratio.
When a diamond is of this shape if the length to width ratio is 1.05 or less the shape is considered square. When the ratio is above 1.05 then it will be rectangular. All other shapes are used to fashion diamonds with a fancy colour.
These shapes include; pears, ovals, marquise, hearts, emerald, Asscher, cushions, princess and specialty cuts.
All the above shapes are considered to have a style of faceting that is called brilliant facets.
The emerald cut and Asscher cut are the two styles that are called step cuts. Due to the optics of step cuts attaining maximum colour strength is difficult and as a result diamonds of this style with a strong colour is rare.
Due to the rarity of diamonds that exhibit a fancy colour, it is extremely critical that the planning from a diamonds rough state to the final gem quality state is paramount, in order to bring forth the Art of Nature of Natural Coloured Diamonds.
