About this item

Product details

Add a bold, natural touch to your plants and projects with these 12 lb black lava rocks. Made from natural volcanic rock, each piece features a deep, uniform black color and a porous, lightweight texture that looks right at home in modern indoor and outdoor settings. Sized at approximately 3/8 inch (6-9mm), they darken slightly when used in water and hold their color over time without staining or fading.

These black lava rocks are a popular choice as a top dressing for succulents, cacti and bonsai. Their clean, decorative look complements minimalist plant styling while adding helpful texture to potting soil. Outdoors, they stand up to sun and rain, making them a dependable option for garden beds, pathway surfaces and lasting landscape features.

Ideal for freshwater aquariums, the varied shapes and rich dark color of these crushed lava rocks make it easy to build slopes, form caves and create a natural-looking aquascape with depth and interest. They are equally useful in terrariums, decorative beds, vase fillers, fire pits and a wide range of DIY projects. With 12 lb of versatile volcanic gravel, you have plenty on hand for planting, crafting and decorating.
