Color of Diamond
When it comes to the 4Cs of diamonds, color, or lack of it, is an
especially important characteristic. Diamonds are given letter grades
to denote the level of color, starting with the letter D for a
flawless, colorless diamond. Why D, and not C, B, or A? The
reason weˇ¦ve heard is that when diamonds started being graded for color
with this scale, it was decided to start with D, to leave room for the
extremely rare possibility that a diamond would be found that was even
more flawless than flawless. It hasnˇ¦t happened yet!
The color grades of D, E and F are the rarest and most colorless. The
gradations in color can only be seen by an expert gemologist. The
grades G-H are called near colorless and the difference can be seen by
a casual observer only when compared to a higher-grade diamond. A stone
in this grade category is an excellent value. The grades I-J are also
near colorless, but not to the same extent as G-H. These also are an
excellent value.
The color grades move up the scale to Z, with an increasing amount of
color. These are inferior gem-quality stones and should not be confused
with canary or other colored diamonds. Colored diamonds are graded
differently than white diamonds and are also highly prized among
collectors. Theyˇ¦re especially beautiful when combined with white
diamonds. Consider that the Hope Diamond, one of the most famous
diamonds, is a rich blue color. Out of all colored diamonds, a red
diamond is the rarest of all.
The colors in colored diamonds come from impurities between the cells
of the crystals, or structural defects. There are many different colors
that diamonds can come in, but theyˇ¦re limited to steel gray, white,
blue, yellow, orange, red, green, pink to purple, brown, and black
