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.
Uses & Applications
Erythrite is a minor ore of cobalt, which is an essential metal used in laptops, batteries, magnets, hip replacements, jet engines, and more. The striking and unusual colors also make erythrite a valued collector's mineral.
