Black Lava Rocks for Fire Pit, 1 Cu Ft, (35 to 40 pounds). Naturally Formed Volcanic Rock Mined in The USA. Varies in Size from 1/2" to 1 1/2"

The size of these rocks were perfect for my fire pit. A very nice mix of small, but not tiny, pieces with the largest being a couple inches. I looked around a lot and I'm glad I picked these considering the quality along with the competitive price.

I wanted black lava rock, and couldn't find it at any of the home improvement stores locally. I found these on Amazon, and thought the price was good. Ordered 3 bags, and then later ordered 1 more. They are perfect! We love them! Seller is great to work with also.

There were too many fines in the two bags I bought. I won't buy from them again.

These rocks worked great for the fire pit and fireplace I used them for. Great variety of sizes and consistent color. I will be using the FirepitOutfitter for all future fire pit and fireplace installs when lava rock is needed.

Really liked the smaller size lava rock for flexibility around burners in fire pit. Quick delivery and quality natural lava rock at a good price. Curing the rock took minimal time.

These worked perfect for my gas fire pit, great price and quality and very fast shipping

The finished product turned out great. I used mine for a landscaping project. I will warn you the are more gray then black and there is color variation with some red mixed in. Size is good. I appreciated being able to gave them deliver to the house

Perfect for simple outdoor fire pit. No issues and my natural gas pits will get extremely hot. I’m so glad I found these and how can you beat prime delivery for Lava Rocks. You can’t! I tried
