Прочитайте текст.
Yellow and brown diamonds are good only for industrial purposes and cost much cheaper than the white and blue ones. But with the coming of nuclear age, the colour of the diamonds can be changed by radiation from a nuclear reactor.
A nuclear reactor emits neutrons which give diamonds a greenish colour.
Beta rays produced by a cyclotron colour the diamonds blue. In both cases the colour changes as a result of the impact of the atomic particles on the diamonds’ structure. The radiated diamonds do not become radio-active and can be worn safely.
