American Fire Products Extra Large Gray Tumbled Lava Stones (4"–6") are oversized natural volcanic fire media designed to create a bold, sculptural statement in large fire pits, fireplaces, and commercial fire features. Each stone is naturally formed and tumbled to achieve a smooth, modern finish that enhances both contemporary and rustic outdoor designs.

Made from 100% natural volcanic rock, these 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 more efficient and visually dynamic flame presentation.

Designed as a top-layer decorative media, these extra-large stones must be installed over a base layer of smaller lava rock to ensure proper burner coverage and optimal flame performance. Ideal for designers and contractors seeking a premium architectural fire feature finish.
