Physical properties
Mohs hardness of 7 for quartz, variable green color from chlorite inclusions, vitreous luster, hexagonal crystal system, and conchoidal fracture.
Formation & geological history
Formed in hydrothermal veins and pegmatites where silica-rich fluids crystallized alongside or over growing chlorite minerals over millions of years.
Uses & applications
Used primarily in mineral collecting, crystal healing, lapidary arts, and occasionally for ornamental display pieces.
Geological facts
Chlorite inclusions often create phantom crystal shapes or mossy green phantoms inside clear quartz points, making them highly prized by collectors.
Field identification & locations
Identify by the characteristic green phantoms or coatings trapped within transparent quartz matrices; commonly sourced from Brazil, the Alps, and the USA.
