Most diamonds of gem quality vary in shade from colourless to yellow. A diamond's colour grade reflects the absence of colour. Therefore diamonds that are classed as white, containing little or no colour, are graded at a higher level than those diamonds which have a visible colour.
The highest colour grading is totally colourless which is graded as "D". As the grade moves along to Z the diamond is considered to be more yellow.
As Divinity Diamond only stocks the highest quality diamonds we do not stock those diamonds with a colour grade lower than L.
