Physical properties
Hardness: 7 (Mohs scale); Color: Brown, tan, and reddish-grey with distinct bands or patches; Luster: Dull to waxy; Structure: Microcrystalline; Specific Gravity: Approx 2.65.
Formation & geological history
Formed from sedimentary deposits of sand and minerals in the Narmada River bed. These are naturally tumbled by the river over long periods of time, though often hand-polished to enhance their shape. They are composed of agate, basalt, and jasper.
Uses & applications
Primarily used for spiritual and religious practices in Hinduism, as well as in the metaphysical community for meditation and energy work. Not typically used in industrial construction.
Geological facts
These stones are collected once a year during a ceremony at the Narmada River in India. They represent the Hindu god Shiva and are considered symbols of both male and female energy (the egg shape representing the male soul and the markings representing the female).
Field identification & locations
Identify by its unique ellipsoidal (egg) shape, brown tones, and distinctive lateral bands/spots. Collectors should look for smoothness and symmetry. They are found exclusively in the Narmada River in Onkareshwar, Madhya Pradesh, India.
