Natural Fancy Orange Diamonds
Natural Fancy orange diamonds range from modified yellow-orange and brown-orange hues to exceptionally uncommon unmodified orange. GIA evaluates hue, tone, saturation, color distribution, and color origin for each submitted stone.
Understanding Fancy Orange Gems
Geological Origin
GIA research identifies several nitrogen-related causes of orange color. Unmodified orange diamonds in its study were colored mainly by the 480 nm absorption band, with isolated nitrogen responsible for most of the remaining examples. Other mechanisms occur less often.
Hue & Secondary Overtones
Orange may appear as an unmodified hue or with yellow, brown, or pink components in the full color description. In GIA's published dataset, fewer than 0.1% of the yellow-or-orange diamonds examined over a decade had an unmodified orange hue. This is a scoped laboratory statistic, not a universal mining ratio.
Market & Valuation
Orange diamonds differ substantially in hue, saturation, modifiers, size, and color origin. These characteristics, together with clarity, cut, provenance, and current comparable transactions, should guide a stone-specific quotation.
Fancy Color Intensity Scale
GIA describes colored diamonds using nine grade terms from Faint through Fancy Dark. The terms reflect hue, tone, and saturation; they are not a linear price scale. See the GIA fancy color diamond grading guide.

Evaluating Orange Diamonds
The 2013 sale of The Orange is a documented historical result for one exceptional diamond. It does not create a general price range for other orange diamonds, which must be evaluated by their complete laboratory grade and individual characteristics.

Orange Diamond FAQ
How rare are natural orange diamonds?
Unmodified orange diamonds are exceptionally uncommon. In a GIA study of naturally colored yellow and orange diamonds examined over a decade, fewer than 0.1% had pure, unmodified orange hues. The figure applies to that dataset and should not be converted into a universal mining ratio.
What makes a diamond orange?
GIA identifies multiple nitrogen-related mechanisms. The 480 nm absorption band was the dominant cause among unmodified orange diamonds in its study, followed by isolated nitrogen, with other mechanisms observed less often.
What is the most famous orange diamond?
The Orange, a 14.82 carat Fancy Vivid Orange pear-shaped diamond, sold at Christie's Geneva on November 12, 2013 for US$35,540,612. Christie's reported that it set auction records for an orange diamond and for price per carat for any diamond at that time.
