diamond color are the most common, whilst some tinted stones, colored
diamonds, are extremely rare and
valuable. The shades of Diamond Color include yellow, blue, black, pink, red,
orange, green
and
brown. Diamond Color is determined by the impurities or structural defects that cause the
coloration. Pure or nearly pure diamonds are transparent and
colorless - referred to as a white diamond color. For more detailed

Diamond Color
The traditional
color associated with the Diamond is white, or colorless, and is categorised into the following: Colorless, Nearly colorless, Faintly
tinted (usually yellow), Lightly tinted (usually yellow) and Tinted
(usually yellow but may progress to brownish). The color scale for
colorless diamonds goes from 'D' (colorless) to 'Z' (dark yellow). The
amount of yellowish color decreases the value of a "colorless" stone.

Natural Diamond Colors
Natural Diamond colors are
ranked according to their rarity and value. The information details what
causes the different natural diamond colors:
-
The Blue Colors are caused by the presence of the
element Boron (B) which changes the conductivity of the diamonds
-
Red, Pink & Brown Colors
are caused by crystal lattice defects during the formation of
the diamond
-
The Yellow Colors
are caused by the presence of the element Nitrogen (N)
which changes the conductivity of the diamonds
-
The Green Colors
are caused by exposure to the natural radiation in the
earth such as uranium ore
-
"Black" diamonds are not truly black, but rather contain
numerous dark inclusions that give the gems their black diamond
color
Factors affecting
the Colors of Diamonds
Factors affecting
the colors of diamonds include fluorescence and color enhancements such as high
pressure, high temperature treatment and irradiation. The process called
Irradiation is used to change the colors of diamonds, these are called
the treated stones. Synthetic colored diamonds are not natural as
they are created in a lab. Synthetic stones are much cheaper than
natural colored diamonds making them easily affordable to everyone.
