Named in 1800 by Abraham Gottlob Werner from the Latin "rutilus", meaning "reddish."
The most common member of the Rutile Group.

Rutile is one of the five forms of titanium dioxide found in nature.

Sellaite (magnesium fluoride, MgF2) also has a rutile-type structure.

Compare 'UM1987-04-O:Ti'.

Commonly prismatic, often slender to acicular [001]. Prism zone vertically striated or furrowed. Usually terminated by {101} or {111}; {001} rare. Rarely pyramidal. Granular massive.
On {011} common. Often geniculated; also contact twins of very varied habit. Sixlings and eightlings at times, occasionally polysynthetic. The twins are sometimes distorted by extension of a pair of faces on {011}. Twin gliding observed on this plane as well. Also on {031}, rare. On {092}, as twin gliding plane.
