Physical properties

Hardness: 7.0 (Mohs scale); Color: Brown, grey, and ochre with distinctive banding; Luster: Waxy to vitreous; Crystal Structure: Trigonal (microcrystalline); Specific Gravity: 2.6 – 2.7.

Formation & geological history

Formed through the accumulation of fine-grained silica and mineral oxides in a riverbed environment. These specific specimens are naturally tumbled and shaped by the current of the Narmada River in India over millions of years.

Uses & applications

Primarily used for religious and spiritual purposes in Hinduism, as meditation aids in holistic practices, and as unique collector specimens for those interested in river-smoothed stones.

Geological facts

These stones are gathered once a year during a ceremony. The markings are unique to each stone and are often interpreted as symbols of the union of male and female energies in Vedic philosophy.

Field identification & locations

Identifiable by its distinct elliptical, egg shape and concentric or 'thumbprint' banding patterns. In the field, look for smooth, water-worn jaspers along river banks, though true Narmada Lingams are geographically specific to the Narmada River in Madhya Pradesh, India.
