Shiva Shell is a stunning natural gem found in the shallow ocean waters off Thailand and Indonesia. Named after the Hindu God Shiva, It’s actually the protective door of the Turban Snail’s shell which, after it dies, detaches and sinks to the seabed. All shells have the spiral but, like all organic gemstones, vary slightly. Set in silver with silver earwires.
