At Keystone Granite, all of our stone comes directly from our two family-owned quarries in Huntsville—Luckey Quarry and our Highway 60 location. Every piece is blasted, cut, and processed on-site, giving us full control over quality and allowing us to offer truly customized granite products for your home or commercial project.
​
From initial cut to final finish, craftsmanship and attention to detail are at the core of everything we do.
