Lustrous Rutile Crystal on Matrix - Georgia
This specimen contains a nearly perfect, deep red-black rutile crystal with a metallic-like luster, on matrix. Some smaller crystals can be found throughout the matrix as well. There are very few scuff marks on the crystal.
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.
