4.2" Roselite on Hematite-Included Calcite Crystals - Morocco

This specimen contains magenta-pink roselite crystals coating about a third of a bed of beautifully terminated calcite crystals. The orange inclusions that sit deep within the calcite crystals are tinted orange due to a hematite inclusion..

Roselite is an arsenate mineral in the monoclinic crystal system. It gained its name not from the rose color that is generally exhibited by the mineral, but was in fact named in honor of a German mineralogist by the name of Gustav Rose. However, the name is quite fitting, for roselite typically displays a vitreous rose-red to pink color. Darker colored crystals have been known to frequently display marked color zoning due to variations in molecular composition.

Roselite has the chemical formula Ca2Co(AsO4)2 · 2H2O, meaning it contains arsenic. While it doesn't pose an immediate health risk from purely handling, ingestion in significant amounts and/or crushing and inhaling roselite can be toxic. For this reason, we suggest washing hands after handling and keeping out of reach of children.
