Forms an isomorphous series with strengite.
Origin of name: namd by German mineralogist August Breithaupt, who firstly described the mineral in 1837, after Variscia, the Latin name of the Vogtland area in Saxony, Germany, with the type locality, Messbach, a village which in 1994 became part of the city of Plauen.
Synonyms and trade names: lucinite, sphaerite, sometimes called variquoise in France

Localities: at the time of writing (2025) about 350 localities are known. However, with the exception of two American locations in Utah and Nevada, most deposits are rather small and not very productive. Noteworthy localities are in Canada, Germany, Spain, Poand, France, Austria, Belgium, Bulgaria, Brazil, Chile, Bolivia, Argentina, Australia, China, Namibia, Mocambique, South Africa and many more
Handling: despite its relatively low hardness variscite is a popular ornamental stone, often used in silver jewellery instead of the much more expensive turquoise. Very sensitive to acids!
