Natural Tiger Clam Lava Shell
The natural Tiger Clam Shells are from the Philippines and are composed of calcium carbonate.
The clams are collected by local free-divers and the shells are removed so the clam can be prepared for food.
The shells were previously discarded as waste, but now local islanders are employed to sort through them looking for the right size, shape, and symmetry.
They are then sand polished, so they are nice and smooth and bonded together.
Because they are natural, they will come in different shapes, sizes, and thicknesses.
Lava Shells are the world’s first self-heating massage tool.
