Choose the right cut of your diamond
A diamond can be put in your wedding ring in many different ways. What you have to take care of is that the diamond matches your ring. The proportions must be right. If you choose for brilliant, pay attention to the size of the stone. A brilliant has a dot at the bottom. It is so annoying when this dot stings in your finger!
The determining factor in the colour of diamonds are the (chemical) elements, which are present. When we look at white diamonds – so the scale above – nitrogen plays the biggest role. Less Nitrogen means more pure Carbon, which in turn results in transparency. Conversely, more Nitrogen will provide the yellow and brown shades.
Fantasy coloured diamonds
What kind of colours are these? Many colours have already been discovered and there are pink to red and blue to green diamonds. Each colour also has its own gradations in vibrancy, making almost every conceivable colour possible.
How do diamonds with fantasy colours get their colour?
Red diamonds: Pure Carbon with a deformed crystal structure to create a red tint.
How is the colour of a diamond determined?
Global colour scale for “white” diamonds
From D to Z means 23 different gradations and does not always communicate easily. For this purpose some letters have been combined into a group with a more descriptive name. These are colourless (D-F); almost colourless (G-j); weak (K-M); very light (N-R); and light (S-Z).
Diamond colour grading scale
To see what colour a stone has, a set of so-called ‘master stones’ is used to look at each stone the diamond in question matches. If the colour of the diamond – under special lighting and precise conditions – corresponds to a master stone, then the gradation is officially assigned.

There are no master stones for fantasy colours and the assessment is very precise work. The color determination is done by lab technicians with years of training and specialization in this field.
