Variscite is named after "Variscia", the historical name of the Vogtland district in Saxony, Germany, where it was originally discovered in 1837. Sources of variscite include Germany, Australia, Austria, Brazil, China, Czech Republic, and the United States.
Since variscite can be bluish green and commonly has matrix veining, it is often confused with turquoise.
Variscite mined in Utah is sometimes referred to as "Utahlite".
