You are bidding on a 12-Pound Pail of Exotic Fire Rock - Tumbled Black Lava Rock.  Black Lava Rock is uniquely formed when hot lava emitted from an active volcano meets the ocean and hardens on contact.  The rocks are gathered from the lava fields in Indonesia and tumbled to create a consistent and more uniform pebble shape and size.  Perfect for outdoor natural gas and propane fire applications, black lava rock radiates heat at high temperatures with cracking or crumbling like other lava rock or cinder lava on the market.  This item is Brand New in its Original Retail Packaging.
