The vast majority of all diamonds contain some nitrogen. In orange diamonds the nitrogen atoms have grouped themselves in a very specific way.This happens during and right after the diamond is formed. These nitrogen arrangements absorb light in the blue and yellow region of the spectrum producing an orange color. Orange diamonds may contain a brown, yellow
or pinkish modifying color.

The majority of orange diamonds come from Africa. The interest in this color surged in 1997 with the auction of the Pumpkin Diamond a 5.54 carats Fancy Vivid Orange diamond with a report from the Gemological Institute of America. The Pumpkin was worn by Halle Berry to the 2002 Oscars when she won best actress for Monster’s Ball.

Currently “The Orange” diamond, at 14.82 carats, is listed as the largest Fancy Vivid Orange Diamond in the world.
