Physical properties

Hardness of 3 on Mohs scale, colors ranging from white, brown, to dark grey with an orange or yellow central spiral, vitreous to pearly luster, orthorhombic/amorphous shell structure.

Formation & geological history

Formed naturally as the protective calcareous operculum (trapdoor) of marine gastropod sea snails, specifically species of the Turbo genus, found in tropical indo-pacific oceans.

Uses & applications

Commonly used in jewelry, as lucky charms, talismans, and in decorative lapidary work.

Geological facts

Often referred to as Shiva's Eye or the Third Eye, this piece is actually not a stone at all, but the fossilized or discarded hard calcareous operculum of a sea snail. In spiritual traditions, it is believed to ward off the evil eye and stimulate spiritual growth.

Field identification & locations

Found washed ashore on beaches in tropical regions, particularly around coastal areas of the Indo-Pacific like Thailand, India, and Indonesia. Recognized by its distinctive circular shape and natural spiral design.
