What is Erythrite?
Erythrite is an old and uncommon mineral whose identification only dates back to 1832. When cobalt-rich ore starts to oxidize, the process can leave behind the beautiful blossoming crystals of erythrite. It is relatively high in arsenic content, so extreme caution is encouraged when handling and processing this mineral.
Etymology & Origins
Erythrite was first described in 1832 for an occurrence in Grube Daniel, Schneeberg, Saxony, and takes its name from the Greek έρυθρος (erythros), meaning red.

Key Characteristics
Rock Types of Erythrite
The nickel variety, annabergite, occurs as a light green nickel bloom on nickel arsenides. In addition iron, magnesium and zinc can also substitute for the cobalt position, creating three other minerals: parasymplesite (Fe), hörnesite (Mg) and köttigite (Zn).
Health & Safety Information
- ⚠️Erythrite dust is toxic because it contains heavy metals Arsenic, Cobalt.
