Abstract

Tanzanite is the most valued gemmological variety of zoisite in which V is the dominant trace element and chromophore. However, the exact position and state of V in the zoisite structure are quite enigmatic and subject to many hypotheses based mainly on spectroscopic evidence but lacking any definite structural proof. Therefore, we combined a structure refinement with optical absorption spectroscopy and used two separate theoretical approaches to shed some light on this enigma.
