These modern stones offer all the benefits of traditional lava rock, enhanced by a smooth, rounded shape and a sophisticated speckled finish in rich dark grey to black tones.

Makes the fire pit look amazing
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
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.
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
Good experience
