Why are rubies red and emeralds green? Their colors come from the same metal in their atomic structureCrystal field theory makes predictions about how a transition metal ion’s structure is affected by the other atoms surrounding it. Rubies are mainly made up of the mineral corundum, which is composed ...
Emeralds are mainly made up of the mineral beryl, which is made from the elements beryllium, aluminum, silicon and oxygen. Beryl’s crystal structure is more complicated than corundum’s because ...
