Operculum

Physical Information

An operculum is not a mineral. It is the small "door" of a sea snail. When the snail pulls back into its shell, it closes the opening with this hard lid. The popular pieces come from a turban snail of the Indo-Pacific. They are made of calcium carbonate, like shells and pearls. One side is flat, and the other is smooth and domed, with a spiral pattern in green, brown, orange and cream.

Because of this eye-like spiral, the operculum is often called Shiva's Eye or cat's eye shell. It is used as a natural cabochon in rings, pendants and earrings. It is fairly soft, so protect it from scratches and knocks, keep it away from acids and perfume, and clean it with a soft cloth.

Metaphysical Properties

The operculum is known as a stone of protection, even though it comes from the sea and not from the earth. Its eye shape is believed to watch over its owner and keep away bad luck and negative energy. In many coastal cultures, it has long been carried as a lucky charm.

Shiva's Eye is associated with the third eye chakra and with intuition and clear seeing. It is also linked to the calm, flowing energy of the ocean. Many people wear it as a small daily talisman, or keep it close when they want to trust their inner voice.
