With a theory developed by physicists in the 1920s called crystal field theory, scientists can explain why rubies and emeralds have the colors they do. Crystal field theory makes predictions about how ...

scientists can explain why rubies and emeralds have the colors they do. Crystal field theory makes predictions about how a transition metal ion's structure is affected by the other atoms ...

Rubies and emeralds have the colors they do because, like many substances, they absorb some colors of light. Most visible light, like sunlight, is composed of all the colors of the rainbow: red, ...
