Margo Garden Products 20 lb. Black Lava Pebbles Item Weight:20 fully adjustable premium 20 inBlack Lava Pebbles are uniquely formed when hot lava emitted from an active volcano meets the ocean and hardens upon contact. The pebbles are gathered from the lava fields and tumbled to create a consistent shape and size. Lava pebbles can be used in natural gas or propane fire applications and unlike other lava rock or cinder rock on the market, lava pebbles will not crumble or break down in size.
