Apart for the very few rare diamonds that are completely colourless most diamonds contain trace elements like nitrogen that can cause a tint of yellow or brown colouration. White diamonds are graded on a scale from D-Z with those that fall between “D” to “J” being generally considered to be of true white appearance. Diamonds are assessed using a comparison set of master grading stones which are viewed under controlled lighting conditions. The way that a diamond presents its colour has a lot to do with the quality of the cut of the diamond, the more superior the cut quality the whiter and brighter the diamond will appear.
What is a white Diamond?
A white diamond is any diamond that falls within the gem quality grade of diamonds and is not considered to be of a fancy colour grade. The most common white diamonds can be found from G to I and are considered to be in the standard white range without any noticeable tint of colour. The colour of your diamond is probably the most noticeable of all the diamond quality grades after the cut quality and can make the greatest impression on how people perceive the quality of your diamond.
What colour diamond should I choose?
A “G’ colour is widely regarded as the standard for a white diamond, it shows no yellow or brown tint and is the best choice for quality and value. It is very near colourless and will never look coloured next to a higher grade diamond.
A “H” is very near to the quality of a “G” but can show a subtle variance between stones in this grade. Still very good but just moving into the lower area of the white range.
Diamonds graded “i and J” are still considered in the white range but will visibly display a slight tint of colour. Alone they provide good value and will look very bright and white but when compared to a higher white diamond there is a marked difference on colour.
The “D to F” colour diamonds are the rare colourless range, these diamonds display a superior bright and transparent look. For a diamond that will really stand out there is no better way than to own a diamond in this colour scale.
Colour is the best area that you can spend any extra money on your diamond that will give you a distinct visible improvement to your diamond. We recommend an “E” coloured diamond as the best choice for colour, it is two grades above a “G” and looks as good as a “D” grade without paying the premium for the highest grade.White Diamond Colour Grading Chart
