Although most gem-quality diamonds, when seen
alone, appear colorless to the untrained eye, there are
subtle differences in shade that become apparent to a
trained professional.
Color in a diamond results from traces of other elements that mixed with pure carbon millions of years ago during the diamond's formation. The most common element mixed with a diamond is nitrogen, which gives a hint of yellow. This slight variation in color is almost undetectable. Diamonds with no traces of body color are truly rare.

Our diamonds are color graded in our Gem Laboratory,
using a special diamond light developed for color
grading, or they have been color graded by the
Gemological Institute of America.
To determine a diamond's true color, the diamond is viewed from the side under balanced white light. It is compared to diamonds in a "Master Set" whose colors have been predetermined by the Gemological Institute of America (GIA). A color grade is then assigned according to the diamond's deviation from the truly colorless diamond.
