Physical properties

Formation & geological history

Formed in hydrothermal veins and pegmatites through the cooling of silica-rich fluids. The green chlorite inclusions often form simultaneously or are trapped as the quartz crystals grow. Found in various geological ages.

Uses & applications

Used primarily for mineral collecting, lapidary work (cabochons), and decorative ornamental pieces. Industrial quartz is used in glass and electronics.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Green 'Moss Quartz' or inclusions of chlorite are common in Alpine-type clefts.

Field identification & locations

Identify by its ability to scratch glass (hardness 7) and its lack of cleavage. Look for characteristic green 'mossy' or 'ghost' phantoms within the white quartz body.
