So what is a Shiva Eye? It is actually a protective covering for the entrance to a snails shell, can you believe it? Also
recognized as mermaids’ money, it is thought to be a lucky charm for the fishermen.
The name of Shiva Eye is kept after Lord Shiva, which is a major Indian God worshipped not only in India but also in various other countries of this world. Moreover, Lord Shiva has the third eye on the centre of the forehead, which in this case is linked to the Shiva Eye gem stone.
