American Fire Products Medium Gray Lava Stone (1" - 2") - LAVAST-M
Our Medium Gray Tumbled Lava Stone offers a refined take on rugged fire media. These 1" to 2" stones are made from natural volcanic rock and tumbled to a smooth finish—giving you striking gray tones with the airflow benefits of porous stone. Perfect for large fire features, their size and color create bold contrast against the flames.
Because of their larger size, these stones must be used as a top layer. For proper airflow and burner protection, they should be installed over a base layer of Small Lava Rock or Medium Lava Rock. Once layered, they provide a clean, contemporary finish with reliable heat performance and minimal maintenance.
Big Impact With Smooth, Sculpted Style
Each piece is sorted and hand-processed to ensure uniform quality. The rich gray-to-black palette enhances modern fire pit designs while reflecting firelight beautifully. These stones are lightweight, heat-rated, and built to last without breaking down, even in high-temperature environments.
Durable, Decorative, and Easy to Use
Like all our fire media, these stones are responsibly sourced and packaged in the USA. They’re clean-burning, low-maintenance, and come backed by a lifetime warranty. Just layer 2–4 inches over your base media and enjoy long-term performance and stunning visual appeal.
If you want a premium top layer that’s both eye-catching and built to perform, Medium Gray Tumbled Lava Stone brings natural beauty and lasting quality to your fire feature.
