What is Arfvedsonite?

Arfvedsonite is an iron-rich sodium silicate that forms a prism or needle-like crystals. It was named after the Swedish chemist Johan August Arfwedson, who discovered lithium. A very rare mineral, arfvedsonite is popular among collectors, and the specimens mined in Malawi are particularly popular.

Uses & Applications

Arfvedsonite is prized as a decorative object most often in its natural, attractive crystalline form. This rather rare mineral is at times cut and polished for use in the jewelry industry, where cabochons are cut as two-colored metallic-looking inset stones for rings and bracelets, as well as being fashioned into beads.

Healing Properties

If you only see the darkness within yourself, arfvedsonite may be able to put an end to this; it might just help you to see the light. Arfvedsonite is believed to be a stone of spiritual growth. It connects with the third eye and throat chakras, allowing you to bring order to your thoughts and communicate better.
