Its large surface area promotes a healthy tank environment, and its deep black color provides a striking contrast to aquatic plants. Safe for all life stages, this substrate is easy to rinse and maintain, making it a top choice for discerning aquarium enthusiasts. ## Description Quartz Gravel is the Rolls-Royce of our range. Natural Quartz not only looks wonderful but has also been shown to help reduce the build up in the aquarium. This is partly due to the huge surface area of quartz which offers added space for the establishment of tank cleaning bacteria. Quartz sparkles underwater due to the many light reflecting facets and is a striking substrate that contrasts well with aquarium plants such as anubias and desertcart swords. ## Features - Aquarium Safe - 100% natural - Promotes good bacteria growth because of its large surface area - Contrasts well with a planted tank - Great for Aquatic Plants ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 2,359 Reviews | ## Images ![Diamond Black 10lb, Premium Gravel and Substrate for Aquariums, Fish Tanks and terrariums, 1-2mm - Image 1](https://m.media-amazon.com/images/I/714Ra42cUIL.jpg) ![Diamond Black 10lb, Premium Gravel and Substrate for Aquariums, Fish Tanks and terrariums, 1-2mm - Image 2](https://m.media-amazon.com/images/I/71YW9Ajw33L.jpg) ![Diamond Black 10lb, Premium Gravel and Substrate for Aquariums, Fish Tanks and terrariums, 1-2mm - Image 3](https://m.media-amazon.com/images/I/71GnrdhokHL.jpg) ![Diamond Black 10lb, Premium Gravel and Substrate for Aquariums, Fish Tanks and terrariums, 1-2mm - Image 4](https://m.media-amazon.com/images/I/A1-0NnrGDwL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***T on January 29, 2026* ### ⭐⭐⭐⭐⭐ Review *by S***T on November 22, 2024* ### ⭐⭐⭐⭐⭐ Review *by C***T on February 20, 2026* ## Frequently Bought Together - Aqua Natural Diamond Black 10lb, Premium Gravel and Substrate for Aquariums, Fish Tanks and terrariums, 1-2mm - Aqua Natural Sugar White Sand 10lb Substrate for aquascaping, Aquariums, vivariums and terrariums - majoywoo Natural Coral Driftwood for Aquarium Decor Fish Tank Decorations, Assorted Driftwood Branch 6-10" 3 Pcs, Reptile Decor… --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/270779964-diamond-black-10lb-premium-gravel-and-substrate-for-aquariums-fish](https://www.desertcart.vu/products/270779964-diamond-black-10lb-premium-gravel-and-substrate-for-aquariums-fish) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
