Physical properties

Formation & geological history

Formed in the Narmada River in India. These are sedimentary stones composed of sand and iron oxide that have been tumbled and naturally shaped by the river flow over tens of thousands of years. They are physically harvested during the dry season.

Uses & applications

Predominantly used for spiritual and religious purposes in Hinduism (specifically for worship of Shiva). In the West, they are popular in the metaphysical community as 'energy stones' or 'fertility stones.' Small ones are often used as pocket stones or in jewelry pendants.

Geological facts

According to Hindu tradition, the Narmada River is one of the seven holy rivers of India, and these stones are considered self-manifested (Swayambhu) deities. Every stone is unique in its pattern of coloring and iron oxide markings.

Field identification & locations

Can be identified by their distinctive egg shape and bi-color or tri-color banding (usually a brown base with reddish-brown patches). Collectors should look for symmetry and the smoothness of the river-tumble finish. Found almost exclusively in the Narmada River in Onkar Mandhata, Madhya Pradesh, India.
