2.4" Vibrant, Magenta Erythrite Crystals - Morocco

Erythrite (chemical formula Co3(AsO4)2 · 8H2O) is a soft and delicate secondary mineral, typically forming prismatic crystals in cobalt-bearing deposits. Erythrite from around the world is known for displaying a deep purple luster: crystals from Bou Azzer, Morocco are some of the largest and most magnificent ones around. Finding specimens with large crystals is rather rare, since it is difficult to remove erythrite from its matrix without breakage.

Erythrite contains the toxic element arsenic. While it doesn't pose an immediate health risk from purely handling, ingestion in significant amounts and/or crushing and inhaling erythrite can be toxic. For this reason, we suggest washing hands after handling and keeping out of reach of children.
