## Description

desertcart.com: Black Lava Rocks for Fire Pit, Gas Fireplace Rocks, 3 to 5 Inch, 20 lbs : Patio, Lawn & Garden

Review: These Rocks Look and Work Great - Perfect. Exactly what I needed. The rocks are a darker gray more thank black but they’re absolutely gorgeous and work great.
Review: Good rocks 👍 - Great price compared to others I saw on desertcart and elsewhere. 20lb didn’t go as far as I thought it would but that’s just the nature of the beast, not specific to this product. I love the softer more modern vibe of these rounded lava rocks. They were the perfect finish to my fire pit conversion to propane. Some of the rocks do get soot / black smudges on them from the fire pit that stand out a little compared to the grayish color of the rocks, but it’s not a problem to me (they aren’t truly black rocks, more medium to dark grey after the dust washed off). Photos show the finished look (multiple bags, about five 20lbs), the in progress look with only one 20lb bag added, and then what rocks look like wet vs dry.
