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 resulting in various Diamond Colors
- 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.
