The optical spectra of
green, white, and lavender jadeite have been studied. Ferric iron is
responsible for the color in the green jadeite. It is proposed that
ferrous-ferric iron inter-
valence charge transfer is responsible for the lavender color of
jadeite. (but more recent work has shown that it actually comes from Mn3+)
