Skyflame Natural Tumbled Stones Round Lava Rock Pebbles for Fire Pit | 10 Pounds, 1/2-1 Inch, Indoor Outdoor Gas Fire Table, Fireplace Decorative, Garden Landscaping, Cultivation of Potted Plants

These stones look great in my gas firepit. They didn't crack or explode when heated, which was my main concern. A few pieces did get a bit dark from the flames, but you can clean off the soot with a metal brush if you want, or rinse and thoroughly dry them before use unless you want them to explode. I bought 3 bags of the 3–5 inch stones and 3 bags of the 2–3 inch ones. The smaller stones were a better value, with a good amount in each bag. For reference: the first bag filled the middle section of my pit, the second bag filled the front, and the third covered the rest. The larger stones look nice, but you get only about four per $40 bag, which feels pretty overpriced. Since I’d opened the big-stone bag already, I mixed them into the middle section for variety. I think it actually looks better with the mix. Overall, I'm happy with the appearance and the decent heat retention. Price-wise, these were cheaper than many alternatives, but for what is essentially a few pounds of stone, they still feel somewhat expensive. I'd give 4.5 stars if I could but 5 would do I guess…

Perfect to replace the ugly glass rocks that came with our outdoor fire table.

The rocks are just as advertised. Just know that one 15 pound bag isn't enough to cover an average size fire pit. We bought an average size gas fire pit for camping for $150....but one 15 pound bag (for $48 dollars including tax) wasn't enough to fill it. It would take three bags to fill it - but that would be the cost of the fire pit, so not cost effective for us. But for a small pit, these rocks would work great.

Seems to be a great size for what I needed them for - a DIY ammo can fire pit. One bag was enough to cover burner but left enough room in the can to store lighter, wrench, and hose. Kind of spendy for “rocks”, but the aesthetic and function is nice.

I bought these for my gas fireplace to replace the old lava rock. They are smooth and feel as heavy real rock. I recommend washing them off with water as there is a lot of dust in the bag and washing improves the look of the rock. In the pic the rock on the left is unwashed, the right is washed. I got the 10 lb bag, medium sized rock. I could have used more rocks to fill the fireplace, but another 10 lb bag would have been too much. I washed some of the old black, broken up lava rock I had and left it as a base to fill in the missing spots. Oh, and it takes about 24 hours for the rocks to dry. They turn dark gray when wet, but will go back to the original color.

Nice looking rocks but not many at all. You would need to purchase about 4 or 5

Love these so much! I washed them before I added them to my fire pit since there was a lot of dust. It’s clearly enough rocks to cover the bottom. I also added some of my unbroken glass rocks to give it a better look. These are a bit expensive but I’ll probably never have to buy them again. They really hold the heat better than glass ones, and they won’t break into tiny chards… Hopefully 🤞

I used sand on the bottom and put one bag of rocks on top and it was the perfect amount.

Kept fire on for more then 30 min under the rocks but the smell was so strong. They give chemical bad smell that you do not feel safe to grill food on them
