*by D***N on 12 August 2024*

I purchased lava rock from Amazon, expecting a natural, porous material as shown in the product images. Unfortunately, the quality was disappointing. The rocks were not porous at all, which made me question their authenticity. They seemed more like synthetic rocks, possibly made of cement mixed with a foaming agent rather than genuine lava rock. They lacked the lightweight, airy texture typical of real lava rock. Overall, I felt misled by the product description and images. I wouldn't recommend this purchase to anyone looking for authentic lava rock for their garden or aquarium.
