3.7" Rutile Crystal Cluster - Graves Mountain, Georgia
This specimen contains large, deep red-black rutile crystals with mirror-like luster, on a rutile-pyrophyllite matrix with small amounts of quartz. Some of the rutile crystals have slight scuffing, as many rutile specimens from this locality commonly 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 known 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.
