The name rutile was first introduced by the German geologist Abraham Gottlob Werner in 1800 (cfr. Lampadius 1800 and Ludwig 1803). The name is from the Latin rutilus, meaning "reddish." The mineral was already known under other names, such as "red schorl" and some other names, some of them later recognized as synonyms or varieties.
I. von Born was the first who described the mineral, in his catalog (1772: 34), as Basaltes crystallisatus ruber [Red crystalline schorl, the latin Basaltes was at the time used for both "schorl" and basalt columns]. The locality given by von Born was Murán near Revúca, Slovakia (Papp 2004). Romé de Lisle (1783) used the name schorl rouge ou purpre [red or purple schorl] for a mineral found as inclusion in quartz from Madagascar. Later, in 1796, De Saussure described sagenite from St. Gothard in Switzerland. Sagenite is now recognized as a variety of rutile, see Sagenite (of Saussure). The element titanium was described by Klaproth (1795) from a specimen of hungarischen rother schörl (huangarian red schorl) from what is todays Slovakia. Richard Kirwan (1796) described the mineral under the name titanite (in Mindat see the entry titanite (of Kirwan)) and Haüy (1801) used the name titane oxydé.
The most common member of the Rutile Group. Rutile is one of the five forms of titanium dioxide, TiO2, found in nature.

Sellaite (magnesium fluoride, MgF2) also has a rutile-type structure. Compare 'UM1987-04-O:Ti'.

Note on the type locality:
Since Werner introduced rutile in 1800, Horcajuelo de la Sierra (originally erronously reported as Cajuelo) in the province of Burgos in Spain has been regarded as the type locality of rutile. A study by Papp (2004, 2007) has show that the type locality should be Revúca, Slovakia . See also the messageboard at https://www.mindat.org/mesg-7-429614.html.
