2.6" Metallic Rutile Crystal on Matrix - Georgia

Rutile is an oxide mineral composed primarily of TiO2, though iron is a typical chemical variation. It comes in a wide variety of crystal forms, from lustrous metallic-looking crystals and thin straw-like crystals to even deep red crystals with slight translucence. Rutile also forms needle-like inclusion with other minerals, most commonly with quartz. Rarer polymorphs of rutile (TiO2) include anatase and brookite, both of which have unique crystal structures.
