This chart shows the range of colour for orange-yellow diamonds and their relative position in the GIA Coloured Diamond Scale. The term brown is associated with weaker and or darker hues, so the predominantly brown colours are located toward the lower left of the chart. Fancy Vivid and Fancy Intense are generally the most coveted grades for fancy colour diamonds. The warm colour of these diamonds reminds us of the progression of fall leaves from yellow to orange to brown!
