Why is a boron doped diamond xtal blue ?

hello :)

Unfortunately I am not able to find the quantitative description of how a concentration of 1ppm Boron doped in a diamond crystal can produce a blue color such as the http://en.wikipedia.org/wiki/Hope_diamond" ?

The doped boron creates an energy gap of 0.4 eV above the valence band.

I will be really thankful for a quantitative description of the process.

Thanks in advance.

You have a reference for this?
