Numerous growths of fanned epidote shooting out of a plate of matrix. In contrast with most other examples of the mineral species, many specimens from the Kharan District show a much darker color and much greater luster, along with this characteristic formation. This is a fine piece from the locale, and makes a great display piece with no stand needed.

Epidote mineralization at Zard Koh (Zard Mountain) occurs within alpine-type fissures of metamorphic origin. The crystallization process produced exceptional dark-green prismatic crystals under moderate to high-pressure conditions during regional metamorphism associated with the Himalayan orogeny. The specimens exhibit remarkable crystal development, displaying characteristic monoclinic morphology with sharp terminations and distinctive striations parallel to the b-axis. The mineral formation occurred through hydrothermal alteration of calcium-aluminum silicates under conditions of greenschist to amphibolite facies metamorphism.
