Diamond Color
Although diamonds are usually thought of as
being colorless, they occur in all colors.
( the Hope diamond, for example
is blue.)
Color has two meanings in the diamond industry. Usually, it refers
to an absence of color - a diamond said to have "fine color"
frequently has no visible color at all. On the other hand we
use the term fancy color to describe naturally colored diamonds
with distinct, attractive tints.(Artifically colored diamonds
are called treated).
Most diamonds are slightly yellow or brown, and are graded by
how closely they approach colorless; the less color, the higher
the value. But with fancy colors, the grade and value increase
with color intensity.
