Lightweight 3/4–1 1/2" black volcanic rock for beds

Black lava rock is crushed volcanic stone full of tiny air pockets, which keeps it light and easy to spread. It goes down like mulch but doesn't rot, fade like dye, or need replacing every year. The dark charcoal color sets off green plants and light hardscape, so it's popular in modern beds, around succulents, and along borders. Pieces run about 3/4 to 1 1/2 inch. Size varies slightly and shade varies by location.

Black lava rock is lightweight, porous volcanic stone about 3/4 to 1 1/2 inch in a dark charcoal color, not dyed mulch that fades.

Also called: black lava stone, black cinder, black volcanic rock, black scoria, black lava gravel, charcoal lava rock.

While I cannot speak to the actual service, I did enter my phone number to get a quote. I realized it was probably too much for my small project. But I received a very helpful follow up text conversation, and after I explained it was probably more than I needed, they still took time to help me work through how much I would need, and offered me possible solutions, even knowing I wouldn't be using their product. Makes me wish they had fit my needs, if that's the level of service they provided even to a non customers

Just a little hiccup in the delivery date but everything worked out well and with great communication from Janel. Ordering went smoothly as well as working with the delivery team to deliver to the appropriate location for my yard.

They were quick to reach out to me and fixed a typo of what I was looking for soil wise for my Raised Garden bed. But shout out to Hello Gravel for being quick to reply!

Frequently Asked Questions

Use the calculator with your length, width, and depth. A 2 to 3 inch layer gives full coverage. One cubic yard covers about 105 square feet at 3 inches deep.

Lava rock weighs about a third as much as most gravel. Selling it by volume means you pay for coverage, not weight.

It's a natural dark charcoal to black. Some pieces show a brownish or reddish tint, and the surface looks lighter when dry and darker when wet. Shade varies by location.

Dark stone warms up in full sun, more than light-colored rock. That's fine for shrubs, succulents, and heat-loving plants. Keep a little space around the stems of tender plants.

It's rough and porous, so wear gloves when you spread it. It's not a good fit for bare-foot areas, play areas, or dog runs.

By dump truck, straight to your property. The driver dumps it in one pile where you choose. Pick a firm, level spot the truck can reach, clear of cars and overhead wires. Delivery is included in the price you see.
