Osumilite is a rare potassium-sodium-iron-magnesium-aluminium silicate mineral. Osumilite is part of the milarite group of cyclosilicates. Osumilite chemical formula is 2312O30, it is translucent and the typical coloring is either blue, brown, or gray. It has a vitreous luster. Osumilite has a hardness between 5-6 on the Mohs hardness scale; the hexagonal crystal structure of osumilite is an unusual molecular make-up. The primary unit is a double ring, with a formula of Si12O30. Normal cyclosilicate have rings composed of six silicate tetrahedrons. In a double ring structure, two normal rings are linked by sharing six oxygens, one from each tetrahedron in each six membered ring.
