Physical properties

Formation & geological history

Formed in hydrothermal veins and metamorphic rocks where silica-rich fluids crystallized alongside calcium-aluminum-iron silicate minerals like epidote or chlorite species.

Uses & applications

Popular among mineral collectors, crystal enthusiasts, and lapidary artists for cabochons, carvings, and decorative display specimens.

Geological facts

Epidote inclusions in quartz often create striking 'phantom' crystals or moss-like green patterns embedded inside clear or milky quartz crystals.

Field identification & locations

Identified by its hard quartz matrix (scratches glass) combined with distinct yellowish-green to deep olive green secondary mineral encrustations or inclusions. Found worldwide in alpine-type veins, pegmatites, and metamorphic terrains.
