Formation & geological history
Formed as river-tumbled stones in the Narmada River, India. These are sedimentary rocks composed of jasper with impurities of iron oxide (hematite) and agate, shaped naturally by river currents over thousands of years.
Uses & applications
Primarily used for spiritual and religious practices in Hinduism, meditation aids, decorative items, and metaphysical collecting.
Geological facts
The Shiva Lingam is found only in the Narmada River in Onkar Mandhata; the markings are unique to each stone and are said to represent the markings on Lord Shiva's forehead. They are traditionally collected once a year during a specific ceremony.
Field identification & locations
Identify by its unique elliptical or egg-like shape and distinctive banded or patched earthy colors. Collectors should look for smooth surfaces and clear, symbolic color patterns. They are primarily harvested from the Narmada River in India.
