Its composition, characterized by sodium, iron, and magnesium, contributes to its dark hues and is often confused with other dark minerals such as black tourmaline (schorl) or biotite mica due to its similar appearance. The chemical formula of Arfvedsonite is (Na_3(Fe^{2+}, Mg)_4Fe^{3+}[Si_8O_{22}](OH)_2), indicating a complex structure with sodium, iron, magnesium, silicon, oxygen, and hydroxyl groups. Arfvedsonite forms in igneous rocks, particularly in nepheline syenites and related environments. It is associated with alkaline igneous complexes, where it can crystallize from sodium-rich magmas.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eCustom Requests: Have specific preferences?\u003cbr\u003eLeave a message with your order, and we'll do our best to accommodate your requests if possible.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eHandmade items vary in size, shape, and color when selected randomly (the highest quality items are chosen first).
