American Fire Products Medium Gray Lava Stone (1" - 2")

American Fire Products Medium Gray Tumbled Lava Stones (1"–2") deliver the perfect balance of natural beauty, performance, and modern fire feature design. Made from 100% natural volcanic rock and tumbled to a smooth finish, these stones feature rich gray-to-black tones that enhance flame visibility and create a clean, contemporary fire aesthetic.

Engineered for high heat resistance and long-lasting durability, these lava stones will not crack, melt, or fade under extreme temperatures. Their porous structure promotes improved airflow, resulting in a brighter, more efficient flame presentation for both residential and commercial fire features.

Designed as a top-layer decorative media, Medium Gray Lava Stones must be installed over a base layer of smaller lava rock to ensure proper burner protection and airflow. Once layered correctly, they deliver a premium, architectural fire feature finish with minimal maintenance and maximum visual impact.
