Diamond
Color:The
color grade of a diamond refers to the degree of color present in the
diamond. Most diamonds have a slight trace of yellow, brown or gray body
color. With the exception of a few fancy colored diamonds in deep shades
of blue, red, purple and pink, the colorless grade of diamonds is the
most rare. Everything else being equal, other than the fancy colors, the
closer a diamond is to colorless, the more valuable it is. The
Gemological Institute of America (GIA) created an alphabetic color
grading scale for diamonds. Diamonds with the least amount of color are
classified as D. Going down the scale, the diamonds with the most color
given a Z rating. Most of us cannot tell the difference between an F
color diamond and a G color diamond until you see the difference in
price.
Small changes in color can result in large changes in the price.
Most jewelry 
stores sell
diamonds in the F to L color range. If you purchase diamonds graded D to
G in color, you may want to set the stone in white gold or platinum to
enhance the stone's beauty. If you purchase a diamond in the H to L in
color, set the stone in yellow gold to give the stone a more colorless
feel.
