Black 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.
Pebble size 3/4" - 1 1/2"
Sourced from lava fields
Tumbled to create a more uniform shape and unique look
Used in natural gas or propane fire pit applications only
Pebble calculator: rectangular fireplace/fire pit， (length x width x height) / 21 = pebbles (lbs.)， round fireplace/fire pit-(diameter x diameter x pebble height) / 26 = pebbles (lbs.)
