It’s sometimes hard to think of the words “diamond” and “colour” at the same time. After all, most people think of diamonds as colourless. In reality, most diamonds in the market range from colourless or nearly colourless to light yellow, brown or even grey-green. This is known as the standard colour range. It’s also called the D-Z range because of the letter designations given to each step in the colour scale, ‘D’ being absolutely ‘colourless’ and ‘Z’ being essentially yellow, on the borderline to ‘fancy.’
