If your landscaping dreams involve slabs so big they come with their own gravitational pull, you’re in the right place. Our Oklahoma Extra Large Slabs are the real deal—massive, dense, and stacked fresh from the earth. These heavy-hitters are typically 5"–7" thick (though some come even beefier) and full of rich Oklahoma color and character.
Use them as natural stone stairs, statement landings, grotto caps, or anywhere you need a little drama and a whole lot of stone. Just a heads-up: you won’t be tossing these in the back of your SUV. These slabs require muscle, machinery, or a group of friends who owe you a favor.
Whether you're building something bold or simply want to drop a jaw or two in your backyard, these slabs aren’t just stones — they’re landscape legends.

Rich Oklahoma sandstone, known for its strength and earthy beauty
