The 5 C's
The criteria when purchasing a natural coloured diamond is slightly different to colourless or white diamonds. Although the 4 C’s still pertain, cut, carat and clarity are less important. The colour is the key factor when considering a natural coloured diamond as all natural coloured diamonds are cut in a way that enhances their colour and brilliance.
Colour is the most important C when grading a natural coloured diamonds. Although there is not necessarily a desired hue, there is a list of criteria that is desired in the colour including, a uniform colour tone throughout, even hue, all over purity and sparkle.How rare the colour is also influences the value of the stone.
The 9-grade GIA colour grading scale runs as follows
- Very Light
- Fancy Light
- Fancy Dark
- Fancy Deep
- Fancy Intense
- Fancy Vivid
Note that when a coloured diamond is graded it is viewed from the top down, as opposed to the normal grading method for colourless diamonds (which are looked at with the bottom, or pavilion up and the top, or table, down).
In coloured diamonds, the cut is incredibly important, while ensuring that as little weight as possible is removed from the raw stone during the process. Often, you will see natural coloured diamonds cut in a more unique shape then colourless stones to work around any impurities in the colour and to get the most uniform colour possible.
As much carat as possible is always tried to be saved to make the stone as large as possible. Although if some carat has to be sacrificed to get an even coloured stone, it will be done.
Impurities in clarity are tolerated in natural coloured diamonds. Although it is not desirable to have impurities that can be spotted by the naked eye, often clarity will be accepted if the colour is even and exceptional.
