The pink color in manganese-containing near-colorless to pale pink stones can be greatly increased by irradiation with gamma-rays or electron beams.
Numbered clockwise from left bottom: (1) 2×2 mm initial; top row (2,3,4) irradiated by different doses of 2 MeV electrons; bottom right (5,6) irradiated by different doses and annealed at 800 °C. Sir William Crookes , a gem fancier as well as a chemist and physicist , was the first to discover radiation's effects on diamond color when in 1904 ...
