You can get your typical red jagged lava rock pretty cheap, but I generally don't find this color, size, or shape locally. So I went ahead and spent the money, and happy I did. These rocks look fantastic in the fish tank, especially against a light sand substrate. Added bonus is that the pours promote the growth of beneficial bacteria. They do come out of the bag extremely dusty and look much lighter. I gave them a quick rinse in tap water and put them right in the tank. Review: Perfect for my broil on my stove - It was exactly what I needed for my stove ## Features - SMOOTH TUMBLED FINISH, NOT JAGGED LAVA ROCK β€” Unlike traditional porous lava rock, these stones are hand-tumbled to create a smooth, rounded shape with no sharp edges. The result is a clean, modern look that complements contemporary gas fire pits, fire bowls, and gas log sets beautifully. - EXTRA LARGE 3"–5" SIZE FOR A DRAMATIC STATEMENT LOOK β€” Each stone measures 3 to 5 inches, making them ideal for larger fire pits and outdoor fireplaces where smaller stones get lost. One 10-lb box covers approximately a 12"Γ—12" area in a single layer β€” use 2–3 boxes for a full fire pit bed. - HIGH TEMPERATURE RATED β€” IMPORTANT SAFETY NOTE β€” Made from 100% natural volcanic lava stone that withstands extreme heat without crumbling, cracking, or discoloring. Safe for use with gas burners indoors and outdoors. Important: always allow stones to dry completely before use β€” wet or damp stones can pop or crack when exposed to high heat. Not recommended for wood-burning fireplaces. - MIDWEST HEARTH β€” A BRAND YOU CAN TRUST β€” Midwest Hearth has been a trusted name in hearth and fire feature products for many years, serving thousands of satisfied customers across the US. Every order is packaged at our Minnesota facility, where broken or compromised stones are removed before your box is sealed. US-based customer support backed by a 30-day satisfaction guarantee. - VERSATILE INDOOR AND OUTDOOR USE β€” Perfect for gas fire pits, propane fire bowls, modern gas log sets, and decorative fire features both indoors and outdoors. Stack stones above your gas burner to create a natural flame effect, or mix with other Midwest Hearth sizes for a layered, custom look. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06XYCVQQT | | Best Sellers Rank | #21,984 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #26 in Decorative Fire Pit Glass Pellets | | Brand | Midwest Hearth | | Brand Name | Midwest Hearth | | Customer Reviews | 4.5 out of 5 stars 665 Reviews | | Flavor | Natural Volcanic Lava Stones | | Item Form | Stones | | Item Weight | 10 Pounds | | Manufacturer | Midwest Hearth | | Manufacturer Part Number | MH Tumbled Stones | | Material | Stone | | Material Type | Stone | | Model Number | MH Tumbled Stones | | UPC | 645360706355 | | Unit Count | 10.0 Count | ## Product Details - **Brand:** Midwest Hearth - **Flavor:** Natural Volcanic Lava Stones - **Item Form:** Stones - **Item Weight:** 10 Pounds - **Material:** Stone ## Images ![Midwest Hearth Natural Tumbled Lava Stones for Gas Fire Pit and Fireplace | Extra Large (3"–5") | Smooth Round Volcanic Rock | 10 Lbs - Image 1](https://m.media-amazon.com/images/I/913pvPe0niL.jpg) ![Midwest Hearth Natural Tumbled Lava Stones for Gas Fire Pit and Fireplace | Extra Large (3"–5") | Smooth Round Volcanic Rock | 10 Lbs - Image 2](https://m.media-amazon.com/images/I/71LRZ71nXTL.jpg) ![Midwest Hearth Natural Tumbled Lava Stones for Gas Fire Pit and Fireplace | Extra Large (3"–5") | Smooth Round Volcanic Rock | 10 Lbs - Image 3](https://m.media-amazon.com/images/I/81gyPfhH46L.jpg) ![Midwest Hearth Natural Tumbled Lava Stones for Gas Fire Pit and Fireplace | Extra Large (3"–5") | Smooth Round Volcanic Rock | 10 Lbs - Image 4](https://m.media-amazon.com/images/I/81uPL-7ojpL.jpg) ![Midwest Hearth Natural Tumbled Lava Stones for Gas Fire Pit and Fireplace | Extra Large (3"–5") | Smooth Round Volcanic Rock | 10 Lbs - Image 5](https://m.media-amazon.com/images/I/71t12F2bn2L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 3-5 inch size Great fish tank decor *by G***O on August 7, 2023* I didn't want to spend the money for these lava rocks.

They are the size we wanted and the color is nice too. We did a layer of black fire glass first then set these on the perimeter of the flames, as suggested by our local fireplace dealer (yeah, that’s a thing). ## Frequently Bought Together - Midwest Hearth Lava Stones for Gas Fire Pit and Fireplace (X-Large (3"- 5")) - American Fireglass Medium Lava Rock, 1/2" - 1" | Use in Fireplace, Fire Pit or Bowl | Outdoor & Indoor Volcanic Rock for Natural Gas or Propane Fires | Decorative Landscaping | 10 lb Bag --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/80110361-midwest-hearth-natural-tumbled-lava-stones-for-gas-fire-pit](https://www.desertcart.co.za/products/80110361-midwest-hearth-natural-tumbled-lava-stones-for-gas-fire-pit) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-11*
