Black & Reddish-brown Lava Rock

Use this lava rock to renew or replace the original rocks that come with a gas log set to make the unit have a realistic look. Distribute the lava rocks liberally over the sand or vermiculite in the firebox to restore the newness and realism of the fireplace. Used to decorate both natural gas or propane (LP) gas units. Mostly black in color with some reddish-brown mixed in.
