Mozambique
near Mavuco
Muva
Gem quality rossmanite occurs in crystals of mixed elbaite-rossmanite
compositions. At this locality, there is
no correlation between the color of the sample and the species of
tourmaline. Pink, pale yellow and yellow-green crystals have been shown
to be rossmanite by electron microprobe analysis (Laurs et al. 2008).
