Clinozoisite has the same chemical formula as zoisite, but it is a member of the monoclinic crystal system. It forms in a series with epidote, but it lacks the required amount of iron in its chemical formula to qualify as epidote. Clinozoisite can be colorless, gray, green, yellowish green to pale yellow, brown, and pink. This gem was first discovered in East Tyrol, Austria in 1896. Crystals are typically elongated and have parallel striations. Specimens from the Skardu Area, Gilgit-Baltistan, Pakistan are highly sought after but noteworthy specimens also come from Europe and the United States.
