3.6" Magenta Erythrite Cystals With Skutterudite

This mineral specimen from Morocco contains lustrous deep purple erythrite crystals, clustered along with skutterudite. Small microscopic quartz crystals line much of the specimen, giving the entire mineral association a beautiful glimmer. What looks to be a small accumulation of roselite druse, can be seen along the edge of the skutterudite matrix, as well (featured above in a close up photo of this specimen).

Erythrite 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, with crystals from Bou Azzer, Morocco having some of the largest and most magnificent characteristics around. Finding specimens with large crystals is more rare than not, due to the difficulty in removing erythrite from it's matrix, without breakage.

Erythrite has the chemical formula Co3(AsO4)2 · 8H2O, 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 erythrite can be toxic. For this reason, we suggest washing hands after handling and keeping out of reach of children.
