Some diamonds are more perfect than others. Clarity refers to the amount and
size of imperfections in the diamond. These may be internal flaws (called
inclusions) and external flaws (called blemishes). Depending on how a diamond
is mounted, some minor flaws can be hidden. The following table is a standard
clarity chart, starting from the highest clarity rating and working downwards.

||Inclusions that are extremely difficult to locate at 10x.

The color grade of a
diamond refers to how closely its body color approaches colorlessness. Most
diamonds have at least a trace of yellow, brown, or grey body color. With the
exception of some natural fancy colors, such as blue, pink, purple, or red, the
colorless grade is the most rare. All things being equal, other than the fancy
colors, the closer a diamond is to colorless, the more valuable it is.
The color grading scale
ranges from totally colorless to fancy yellow. The differences between one grade
and another are very subtle, as can be seen by the number of grades within any
Color refers to the color of the diamond (how easy was that?). Diamond color
is denoted by a color scale used the letters of the alphabet (from D -
"colorless" to Z -"light yellow color"). For a ring, you
are most likely to be looking at diamonds in the first two groups:
||The colorless diamond group is the most expensive. D and E show
virtually no color. F starts to show the very slightest of color and
is the transitional color to the Near Colorless group
||The Near Colorless group is a very popular color group because of
its relatively low price, yet still high color. These colors are hard
to detect in mounted diamonds, showing a very light shade of color.
buyers don't mind a
faint yellow appearance (K,L,M ) because when these diamonds were set
into yellow gold, they appeared very nearly colorless and since this
grade was is expensive the customer could opt for a larger diamond
without increasing their budget.
