Physical properties

Formation & geological history
Formed from sedimentary deposits in the Narmada River, India. These stones are naturally tumbled by the river current over millions of years (geologically linked to the formation of the Narmada valley), which contributes to their unique elliptical shape.
Uses & applications
Primarily used for spiritual and religious practices in Hinduism as a symbol of Lord Shiva. In the West, they are popular for meditation, metaphysical healing, and as home decorative items or pocket stones.
Geological facts
These stones are found in only one place on Earth: the Narmada River in Onkareshwar, India. The red markings are believed by geologists to be bits of meteoritic material that integrated with the local rock millions of years ago, or localized iron oxide staining.
Field identification & locations
Identify in the field by its distinct egg/phallic shape and bi-color or tri-color banding (usually brown/red on an earthy background). They are gathered once a year during a specific ceremony in India. Collectors value them for smooth symmetry and vibrant banding.
