COLOR
Diamonds are found with a range of colors, from faint yellow
or brown through to the very rare pinks, blues, and greens
known as fancies. Although most gem-quality diamonds when
seen alone appear to be colorless to the untrained eye,
there are subtle differences in shade. Color in diamonds
results from traces of other elements which mixed with
carbon during the diamond's formation.
Diamonds with no traces of color are extremely rare and more
valuable.
To determine a diamond's true color, the diamond is viewed
from the side and is compared to diamonds in a Master Set
whose colors have been predetermined by the Gemological
Institute of America (GIA). The color grading scale is from
totally colorless to light yellow.
The difference between one grade and another Is very subtle,
as can be seen by the number of grades within any one
category. |
