Description

As far as I can tell a one-off find of orange bultfonteinite (analysed) on gemmy diopside (analysed) crystals with tiny colourless apophyllite and even a few bakerites hiding in the crevices. It's been hard to photograph as it's so lustrous and light bounces everywhere, Rare new stuff from this deposit that seems to produce rare cobinations in very limited quantities.
