Fancy Coloured Orange Diamonds are one of nature’s greatest abnormalities and in his respected book "The Great Diamonds of the World," published by world famous gemologist Edwin Streeter in 1882 he referred to Fancy Coloured Loose Orange Diamonds as "fire diamonds".

Where Are Fancy Coloured Loose Orange Diamonds Found?
Most Fancy Coloured Loose Orange Diamonds are found in either the famous Argyle mine in Western Australia or in South Africa.
What Gives Fancy Coloured Loose Orange Diamonds Their Colour?
The unique colouration of Fancy Coloured Loose Orange Diamonds is created by the presence of nitrogen within the diamond. Scientists believe that nitrogen atoms are grouped in a hyper-specific way whilst the diamond is forming and when situated in a particular arrangement, they absorb blue and some yellow light, thus producing an orange appearance.
The vast majority of Fancy Coloured Loose Orange Diamonds are classified as Type 1b. This is because nitrogen atoms are not assembled in groups of two, three or four atoms as in Type 1a diamonds. Instead, nitrogen is scattered as individual atoms.
What Shades and Intensities Do Fancy Coloured Loose Orange Diamonds Come In?
Fancy Coloured Loose Orange Diamonds are classified by the GIA in seven intensities: faint orange, very light orange, light orange, fancy, fancy intense orange, fancy vivid orange and fancy deep orange. The most desired hues are fancy vivid and fancy deep. The vast majority of diamonds in the Fancy Coloured Loose Orange Diamond family are considered dark in tone and are weak to moderate in terms of saturation.
As the colour orange is naturally a mixture of the primary colours red and yellow, it is very common to see strong modifiers in orange diamond. Therefore Fancy Coloured Loose Orange Diamonds range from brown-orange to yellow-orange, with most stones having a brown or brownish colour appearance to the naked eye. However it should be noted that to be classified as a Fancy Coloured Loose Orange Diamond there must be an absence of brown within the diamond.
In terms of the colour scale orange is in close proximity to yellow. Typically the modifying colours within Fancy Coloured Loose Orange Diamonds in which the orange is the secondary colour are brown, yellow or pink. In cases where the diamond’s colour is less than 23% orange, it will be deemed "orangey" instead. So for example the GIA classify the overtone shades as: Fancy Vivid Yellow Orange, Vivid Yellow Orange, Fancy Deep Brown Orange, Deep Brown Orange, and Fancy Orangey Pink. A pure fancy vivid orange diamond or vivid orange with a slight yellowish tone (i.e. vivid yellowish orange diamond) is sometimes referred to as "pumpkin diamond" due to the obvious comparison in colour with a pumpkin.
Are Fancy Coloured Loose Orange Diamonds Rare And Expensive And Are They A Good Investment?
