Tumbled Lava Stone for Fire Pits – 10 lb bag

Tumbled Lava Stone is a modern variant of traditional lava rock with all the same qualities and benefits.

Unlike lava rock, lava stones are rounded, smooth, and regularly shaped, with a speckled finish. The beautiful color of the stones ranges from dark grey to black.

The Lava Stones are naturally created when volcanic lava and cool water meet, which causes the stones and harden. Once collected they are put through a ’tumbling’ process, removing any remaining sharp edges and enhancing their uniform shape. Of course, considering their origin, you will not be surprised to learn that they can withstand extreme temperatures without crumbling or exploding.

The smooth, more modern finish of Tumbled Lava Stone makes it incredibly versatile. It looks equally at home in a rustic-looking setting as it does in a contemporary fire pit.

Tumbled Lava Stone is safe for use in both fireplaces and fire pits, indoors and out, and is compatible with both Natural gas and Liquid Propane.

Lava Stone also retains heat far better than logs, making them more energy-efficient and cost-effective.

Great Product

Makes the fire pit look amazing

Brian K. McKay

The lava rocks were extra large as promised. I really need about 40 but I am not sure I want to spend $450 right now. Thanks

Glen Seiler

Very pleased with this product. Just note that 10 pounds is not a lot of 3-4 inch rocks (5-6 rocks). I mixed with smaller 1-2 inch rocks for a great look. Just what I wanted.

James Smith

There was a mix up with our order and I contact the company and they made the correction as requested. We are thrilled with the product. We are thrilled their customer service people made our requested correction. We recommend this company! Thank you
