About Wiluïte

Wiluïte is a rare mineral best known for its rich, earthy beauty and complex crystal chemistry. It belongs to the vesuvianite group and is typically found in metamorphic rocks where limestone has been altered by heat and mineral-rich fluids. Wiluïte often forms in granular masses or short prismatic crystals, showing deep shades of brown, reddish-brown, olive green, or yellow-green, sometimes with a subtle glassy luster.

What makes wiluïte especially fascinating is its unusual composition, which can include elements like boron and iron, giving it distinctive color and structure compared to more common vesuvianite varieties. The mineral was first described from the Sakha Republic (Yakutia) in Russia, one of its most notable localities.
