Named after the type locality at the Teine mine in Hokkaido, Japan. This rare secondary mineral  occurs and a producr of the ozidation of copper- bearing and tellurium-bearing sulfides in only a few localities that include Japan, Mexico, the USA, Belgium, Norway and, purportedly, Russia.

Named after its composition as tellurium (tellur) dioxide where the name for tellurium come from the Latin for “earth,” tellus. Found as an oxidation product of tellurium bearing minerals. It is found in a small number of locations including Romania, Kazakhstan, Japan, the USA, and Mexico.Crystals are acicular, straw yellow to bright golden and glassy.

Named in reference to the relationship to perite and for the dominance of tellurium, with lead, in the bismuth site of perite. It can be found only in California in the United States at the Bird Nest drift, the type locality, and the Aga mine, both in Otto Mountain. It occurs in fracture surfaces and in small vugs in brecciated quartz veins and in association with acanthite, bromine-rich chlorargyrite, caledonite, cerussite, galena, goethite, and linarite. Other secondary minerals occur in the veins. It appears as bluish-green, transparent rounded, square tablets and flakes.
