Abstract
The characteristic blue color of the mineral kyanite is shown to be caused by traces of Ti+++ in the range of a few parts per million. Evidence from the intensity and position of optical absorption bands indicates that the unusually intense color probably arises from electron delocalization into narrow d-bands.Keywords
