2.2" Rutile Crystal - Graves Mountain, Georgia
This specimen contains a large, deep red-black rutile crystal with a metallic-like luster, on a rutile-pyrophyllite matrix. The rutile crystal at the center of the specimen has the typical scuff marks that can be found on many specimens coming out of this locality.
Rutile is an oxide mineral that is composed primarily of TiO2, although iron is a typical chemical variation. It comes in a wide variety of crystal forms, from lustrous metallic-like crystals, thin straw like crystals, to even deep red crystals with slight translucence. Rutile has also been know to form needle-like inclusion with other minerals, commonly forming with quartz. Rarer polymorphs of rutile (TiO2) include anatase and brookite, both of which have unique crystal structures.
