Lava rocks provide a rustic, earthy aesthetic, yet sit very well in both contemporary and traditional settings alike!
Naturally occurring, it forms as volcanic magma rises to the surface, cools, and releases gases, which give these rocks their coarse surface. Because they are volcanic, they can withstand extremely high temperatures without sustaining any damage or crumbling.
PLEASE NOTE: The lava rock varies in color from deep brown to black; this is normal.
American Fire Products’ Lava Rock is responsibly sourced, processed, and packaged in the United States. It is low-maintenance, long-lasting, and qualifies for a lifetime warranty. For best results, apply at least two inches of coverage above your burner and keep your fire pit covered when not in use. Look no further, we supply the best lava rock for gas fire pits.

You might say why do I need support when buying fire pit supplies? There is a science to it and this guy knows his stuff! He will call you back promptly and advise you as to what you need. You don’t get this kind of info at the patio store. The shipments are prompt and affordable.
Had a great experience with working with The Magic of Fire. Shipped quickly and just as described.
