Abstract

The color of yellow-green to yellow-brown Mn-rich elbaite tourmalines from Zambia and Nepal is controlled by Fe^(2+)-Ti^(4+) (brown) and Mn^(2+)-Ti^(4+) (yellow-green) intervalence charge transfer. The proposed Mn-Ti interaction responsible for an absorption band centered at 325 nm is especially well developed in the Zambian tourmaline whose spectroscopic properties are discussed.
