Paper Summary by Mr Keal Byrne “IR-stimulated visible fluorescence in pink and brown diamond”

Keal Byrne
We have seen unusual fluorescence behaviours in natural pink and brown diamonds, when exposed to ultraviolet and infrared light. These behaviours are due to transfers of electrons and energy between different types of defects in the diamond crystal (including defects which cause the diamond’s colour). Understanding these interactions is a step towards finally identifying the cause of pink colouration in natural diamond.
