2.3" Lustrous 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 looks to have broken, shifted and resettled while in the mountain, leaving it with a somewhat bent appearance. Many of the faces didn't seem to be affected by this, for a brilliant mirror effect is still present.

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.
