The coloured diamond, or fancy diamonds as they're referred to are quite rare.
Most diamonds are yellowish brown when in their natural state, which is caused by the presence of nitrogen molecules trapped in the mineral when it was formed millions of years ago.
The less nitrogen in a diamond,the whiter it is and the more expensive and coveted - colour grades go from D - completely colourless, to Z - a beige yellow colour.
All of our diamonds at Monroe Yorke Diamonds are independently graded by GIA, a diamond grading laboratory in the United States. Discernible differences between D, E, and F grades are difficult to see with the naked eye, and when set in a mount, invisible.
Cut grades often change the colour of a diamond. As the colour grade gets nearer to Z, the yellow tinge is much more visible, and when compared to diamonds of a higher grade, the difference will be much more dramatic.
