Decorative Stone Rock
We deliver every gradeLava Rock
Lava rock is chunks of cooled volcanic rock, usually red, black, or brown. It's full of tiny air pockets from gas that got trapped when the lava hardened, so it weighs about half what regular gravel does. Geologists call it scoria. You'll feel the difference the second you pick up a piece.
The name is a catch-all. It covers red lava rock, black lava, and brown lava, which are all the same basic stone in different colors. Sizes usually run from 3/8 inch up to about 3 inches across. Lava rock costs more per yard than crushed stone because it has to ship from volcanic regions in the western U.S., so budget higher than you would for local gravel.

What people use it for
How to choose within lava rock
Read at the right distance
Pick the size that reads from where you'll see it. Fist-sized boulders in a small bed look like debris; pea-sized stone across a big front yard looks like dust.
Color that stays put
Natural stone holds its color for years. Dyed or coated pieces fade to grey after a season or two of sun.
Rounded vs. angular
Rounded stone rolls under a shoe, so it belongs inside a border. Angular stone stays put on a slope but reads harder underfoot.
