American Fire Products Large Gray Lava Stone (2" - 4") - LAVAST-L
Bring bold texture and eye-catching contrast to your fire feature with our Large Gray Tumbled Lava Stone. Each 2" to 4" stone is naturally formed, then tumbled smooth for a polished finish that enhances airflow and elevates flame visibility. Their generous size makes them a standout top layer for expansive fire pits, fireplaces, and commercial installations.
Due to their size, these stones are not designed for direct burner coverage. For safe, efficient operation, they must be installed over a base layer of Small Lava Rock or Medium Lava Rock. Once layered properly, they deliver dramatic flame movement, clean performance, and a premium, architectural finish.
Natural Volume, Modern Finish
Each batch is sorted and hand-processed for consistent size and color. The soft gray-to-charcoal tones pair beautifully with modern and rustic settings alike, while the tumbled texture softens the rugged appearance. These stones are porous, lightweight, and built to withstand high temperatures without crumbling or fading.
Low Maintenance, Big Impact
Like all American Fire Products media, our large gray lava stones are responsibly sourced, sifted, and packaged in the USA. They’re clean-burning, maintenance-friendly, and covered by a lifetime warranty. Apply 2–4 inches above your base layer and enjoy a fire feature that commands attention and performs reliably season after season.
If you’re looking for an oversized lava rock that delivers both visual weight and long-term value, Large Gray Tumbled Lava Stone is your go-to choice for bold top-layer design.
