Product Overview

By Hargrove Hearth Products

If you love the natural look of lava rock but prefer a more refined finish, the Medium Tumbled Lava Stone is your perfect match. These gently rounded 1"–2" volcanic stones offer all the rugged character of raw lava rock—minus the sharp edges and excessive dust.

Tumbled for a smoother surface, this fire-safe media provides excellent airflow and heat dispersion while enhancing the look of your burner system. Use as a top layer, base filler, or standalone media.

  • Gently Tumbled Volcanic Stones – Polished edges with an organic texture
  • Natural Lava Rock – Heat-treated and fire-rated for gas fire features
  • Excellent Heat Dispersion & Airflow – Ideal for burner performance
  • Low Dust, Low Maintenance – Easier to manage than raw crushed lava
