2.2" Lustrous Rutile Crystals - Graves Mountain, Georgia
This specimen contains a beautiful, deep red-black rutile crystal with a metallic-like luster, on a rutile-pyrophyllite matrix. The largest rutile crystal in the center of the specimen looks to have a transverse stress fracture through the center of the crystal, and scuffing around one end. Otherwise, this a truly fantastic rutile crystal specimen.
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.
