Description

Very rich specimen gemmy orange-red Anorthoroselite crystals associated with deep wine-red roselite crystals and dark green cobaltaustinite crystals.

The originally name for Anorthoroselite was beta-roselite, for its being a dimorph of roselite. Renamed to anorthoroselite in 2022, where the 'anortho' prefix is Greek for "not right angle", indicating that it is a triclinic dimorph.

Beautiful and very rich specimen.

PXRD confirmed specimen.
