Lum et al. (2016) report that pegmatites in the
Erongo Volcanic Complex in central Namibia host a variety of
spectacular minerals of interest to museums and collectors. Associated
with beryl from this region is schorl, foitite and rossmanite. They
presented several images of rossmanite present in inclusions in blue,
green and colorless beryl from the Erongo Region.
