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.

Healing Properties

Erythrite is a positive energy stone that works on the Heart, Throat, and Root chakras. It can help a person on their journey to self-awareness, allowing for self-acceptance and spiritual growth. The stone's positive energy on the heart is believed to influence one's relationships and allow for better understanding of others. Communication may be improved when using this stone as it opens the Throat chakra for better clarity when speaking.
