  • Rutile: Mineral information, data and localities.

    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.

  • Rutile Wikipedia

    Rutile is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks.. Thermodynamically, rutile is the most stable polymorph of TiO 2 at all temperatures, exhibiting lower total free energy than metastable phases of anatase or brookite. Consequently, the transformation of the metastable TiO 2 polymorphs to rutile is irreversible.

    Rutile also lends its name to the rutile mineral group. The only other gem-quality member of this group that gets faceted (rarely) is cassiterite. As needle inclusions, rutile crystals occur in a wide variety of gem materials, such as quartz and agate (sagenite). Rutilated quartz pieces can make stunning jewelry stones as well as display specimens.
