The colour grading scale for Orange Diamonds is divided into seven categories:
1. Faint Orange;
2. Very Light Orange;
3. Light Orange;
5. Fancy Intense Orange;
6. Fancy Vivid Orange and
7. Fancy Deep Orange.
These are then further divided based on their secondary colours.
Other colours seen along with the main colour are known as secondary colours. If the secondary colour is rarer, then the diamond will be more expensive.
Always graded face up (flat side up) these diamonds will have the secondary colour listed first, followed by the main colour. The last colour mentioned is the most dominant colour.
Fancy vivid and fancy deep are the mostly desired colour intensities.
Pure Orange Diamonds are extremely rare, as rare as the red.
The colour is caused by the presence of Nitrogen in its composition.
Natural fancy orange diamonds range from orange red to yellow orange.
Red, orange, pink, purple, yellow and brown are the secondary colours. Orange diamonds usually occur with a secondary colour and are also a secondary colour to other diamonds.
In the yellow and pink diamonds, the orange is the secondary colour. When the colour is less than 25 percent orange, it is referred to as “orangey”.
For these diamonds to be classified as orange there cannot be any brown tints. A pure fancy vivid orange diamond or vivid orange with a slight yellowish tone is sometimes known as a “pumpkin diamond”.
Most Orange Diamonds are found in Australia and South Africa.
