Conical conch shell made of mercury

A Shankha is a conch shell of ritual and religious importance in Hinduism and Buddhism. It is the shell of a large predatory sea snail, Turbinella pyrum, found in the Indian Ocean. In Hindu mythology, the shankha is a sacred emblem of the Hindu preserver god Vishnu. It is still used as a trumpet in Hindu ritual, and in the past was used as a war trumpet. The shankha is praised in Hindu scriptures as a giver of fame, longevity and prosperity, the cleanser of sin and the abode of goddess Lakshmi, who is the goddess of wealth and consort of Vishnu.
