Epidote is a mineral species typically forming elongated, prismatic crystals that exhibit a pistachio-green color and a vitreous to resinous luster. The mineral commonly occurs in metamorphic rocks as part of epidote-albite and greenschist assemblages, and it can form robust, well-formed crystals that attract field and cabinet collectors alike. In matrix and vein specimens, epidote often accompanies minerals such as quartz, feldspar, and hematite, while high-quality crystal terminations and color zoning enhance its specimens.

About Epidote

Notable sources include localities in the United States, Mali, Pakistan, Austria, and Peru, where well-crystallized specimens have been reported. Collectors prize epidote for its vivid green hues, variation in crystal habit, and the way it can dominate a specimen's appearance when larger, lustrous crystals are present. Its relatively accessible crystal forms and attractive luster make epidote a staple in many cabinet displays and regional collections.
