Kesterite is a copper zinc tin sulfide mineral with the formula Cu2ZnSnS4. It forms in the tetragonal system and often occurs as prismatic to tabular crystals with a resinous to adamantine lustre and a pale to dark yellowish-brown color. Crystals may display well-formed faces and can form in granular, massive, or occasionally euhedral habits, reflecting its sulfide mineral group characteristics.

About Kesterite
Notable specimens have been reported from China, where high-quality crystals and compact aggregates are found in hydrothermal and skarn-related environments. Collectors value kesterite for its crystallographic forms and the way its metallic luster interacts with light, producing subtle color shifts that enhance its presence in a cabinet of sulfides. While it can be associated with other copper- and zinc-bearing sulfide minerals, kesterite’s distinctive composition and crystal habits often make it a memorable addition to a collection, especially for those focused on copper, zinc, tin sulfides and related paragenesis.
