Dazzling Diamonds

Think diamonds are white with a touch of fire when properly cut? Think again. Diamond collectors Alan Bronstein and Harry Rodman have loaned London's Natural History Museum their dazzling Aurora Collection, which includes 296 naturally coloured diamonds, from emerald green to blood red. Some of these colour varieties are extremely rare; some actually glow and change colour under ultraviolet light. You'll find them in the Museum's Minerals and Meteorites Gallery. Admission to the NHM is free.
