When it comes to the diamonds that are traditionally used in bridal rings, less is more when it comes to color. These are the white or colorless stones. The Gemological Institute of America, one of the world's leading diamond certification authorities, has developed a diamond color chart that assigns a grade to indicate how much chromaticity is present in the stone.
The highest grade of diamond is "D". The reason there are no A, B or C graded stones is because before this chart was implemented in the 1930s, stones were graded "A", "B" or "C". The highest grade are the stones in the "D", "E" and "F" category. These are absolutely colorless and it takes a trained gemologist to tell the difference between the three top grades.
The highest grade is "D". These stones are absolutely colorless. Grades "E" and "F", while still considered colorless, they contain minute traces of coloration that can detected by an expert gemologist. The next tier, near colorless, encompass grades "G" through "J".
Stones graded "I" through "J" are commoner than the higher grades and are therefore less expensive, approximately half what you would pay for a "D"-graded stone. Within this range, the price differential can be 10 to 20 percent from one grade to another.
The next color range are grades "K", "L" and "M". These have a slight tinge of yellow that may be detectable by the naked eye. Set in yellow gold, these stones are often described as "warm" in color. These stones are exceptional value; a "K" stone will be half the price of a "G" stone. Diamonds in the "N" to "R" range have an obvious yellow or even brown tint. They are superb value, mainly because nobody wants them.
Don't waste your time on the lowest grades, "S" to "Z". These have far too much coloration for anybody. While the diamond color chart is a handy guide to price, when it comes to what you like, your own judgement is best.
