Physical properties
Translucent pale green, smooth tumbled surface, vitreous-to-waxy luster; quartz hardness is Mohs 7, with no cleavage and conchoidal fracture. The photograph cannot confirm composition or specific gravity.
Formation & geological history
Quartz forms in hydrothermal veins and igneous or metamorphic rocks; green aventurine gets its color from microscopic mica inclusions. Quartz ranges from Precambrian to recent in age.
Uses & applications
Commonly sold as a decorative or metaphysical tumbled stone; higher-quality green aventurine is used for beads, cabochons, and ornamental objects.
Geological facts
Green color may also indicate prehnite, serpentine, jade, or dyed quartz, so visual identification alone is uncertain.
Field identification & locations
Look for glassy translucence, conchoidal chips, and inability to scratch it with a steel knife; quartz should scratch ordinary glass. Common sources include Brazil, India, Madagascar, and the United States.
