From our Lava Rock Collection, it measures on average 1/2" - 6" and is used as an accessory to our Fire Glass or fire pit. We recommend using Lava rock as a filler if you have a deep fireplace or firepit. For a complete design, add Fire Glass on top to cover the fire rock thoroughly so it will not be detectable. We currently offer lava rock in 10 lb. bags, which is equal size to 20 lbs. of Fire Glass.
PLEASE NOTE:The lava rock will vary in color from brown to black, this is normal.
