American Fire Products Large Gray Tumbled Lava Stones (2"–4") deliver a bold, oversized fire media solution designed to enhance the visual impact of any fire pit, fireplace, or outdoor fire feature. Naturally formed volcanic rock is tumbled to create a smooth, refined surface that balances rugged texture with a modern architectural finish.
These large lava stones are engineered for extreme heat resistance and long-term durability. They will not crack, melt, or fade under high temperatures. Their porous structure improves airflow, helping produce a brighter, cleaner, and more dynamic flame presentation.
Designed strictly as a top-layer fire media, these stones must be installed over a base layer of small or medium lava rock to ensure safe burner coverage and optimal performance. Once properly layered, they create a premium, high-end fire feature finish with strong visual presence.
