The color seen in Diamond is due to impurities of Nitrogen, Aluminum and Boron within the crystal structure, which influence the absorption of light. Visible white light is a mixture of the spectral colors from red, orange, yellow, yellow-green, green, blue-green and blue.
Sample:
1. By low concentration of Nitrogen atoms (1:1 000 000) dispersed through the crystal lattice, the Diamond absorb light in the blue region, disturb the color balance and the Diamond show a yellow color.
2. By traces of Aluminum atoms (1: 20 000 000), within the atomic structure, the Diamond show blue color.
3. By traces of Manganese atoms, within the atomic structure, the Diamond shows pink color.
4. By traces of Boron and Aluminum and missing Nitrogen atoms, the Diamond show blue color and there are goods semi-condutcers.
The color champagne and canary are very intense yellow Diamond.
By smaller Diamond the color appears less intense than by larger stones which absorb more light due to the light rays which travel a longer path trough the Diamond. The color grading is according to the size of the Diamond.
Color can be altered or enhancing, by bombardment, which influence this concentration within the crystal structure.

     Only few companies around the world specialize in colored Diamond, small size mainly mined in Australia, bigger crystals in some mines in Africa.
Maybe sometime in the future you will be a colored Diamond lover.
