Physical properties
Hardness varies from 6.5 to 7 on the Mohs scale, featuring smooth polished surfaces, vitreous luster, and various green, brown, and tan colors.
Formation & geological history
Formed through various geological processes including hydrothermal activity and metamorphism, later mechanically tumbled and polished by humans.
Uses & applications
Widely used in jewelry, crystal healing, decorative items, and mineral collecting.
Geological facts
Tumbling simulates the natural water-wearing process of rocks in riverbeds over thousands of years, but accelerates it using abrasive grit in a rotary tumbler.
Field identification & locations
Collected worldwide as polished pocket stones; identification depends on specific mineral testing since tumbling removes original crystal faces.
