- Colours D,E & F are obviously the best but they are also the most expensive . Choose these if you are typically the kind of person who wants the best for yourself
- G & H on the other hand provide excellent value. Even GIA defines them as near colourles and the colour on a G & H coloured diamond are undecipherable to the naked eye
- I,J,K are great if you are on a budget. K colour diamonds may have faint traces of yellow but if you are looking to set them in Yellow Gold, then no one can see the difference
Now you may ask “why does the GIA Colour Grading system” start at D and not at A as would be expected. The reason is this… Before GIA put together the current colour grading system, different jewellers were using different colour grading scales. These included alphabet (A,B and C), numeric (0,1,2,3, etc.), Roman (I, II, III) or even descriptions like “clear white”,”blue-white”, etc. This obviously resulted in a lot of inconsistency. When GIA created their colour grading scale, they wanted to start afresh and therefore they decided to start with “D” which did not have any association with premium colours in the previous grading scales. We’ll write subsequent posts explaining the other 3 C’s in details and also explaining the differences between each of the individual colour grades.
