Although most gem-quality loose diamonds 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 elements that mixed with pure carbon millions of years ago during the diamond's formation. The most common element mixed with diamond is nitrogen, which gives a hint of yellow. Diamonds with no traces of body color are truly rare.

Our diamonds are color graded in our Gem Laboratory which has been accredited by the American Gem Society (AGS) and uses a special diamond light developed for color grading. In addition, some have been color graded by the Gemological Institute of America (GIA).

Lux Bond & Green also offers natural "fancy" color diamonds such as fancy yellow (canary), pink, blue, and cognac.
