Cornerstone Materials Stone Quarry

Our History:
We began mining and distributing random and fabricated Arizona flagstone over 20 years ago. However, in the mid nineties, then operating as American Sandstone we purchased one of the oldest and largest sandstone quarry claims in Arizona. Today, we still have nearly the same mining supervisors and staff that we did when we started.

How we produce:
Our sandstone is produced by using explosives to loosen the earth for easier block removal. These blocks are split by hand, forcing steel chisels into the natural seams that run parallel through the stone. These seams determine the thickness of the flagstone. The smoothness of the stones face depends on how tight the natural seams is and how easily it splits. We then truck our stone into our yard where it is sorted to the proper thickness and color and put into inventory ready to ship.

How we distribute:
We sell most of our products through independent stone distributors throughout the United States. However we do sell directly to the local public through our retail yard in Chino Valley Arizona, but we may make exceptions to out-of-state customers where we have no distributor in their area. We are always looking for viable distributors for our random, dimensional or thin veneer products.

What we produce:
The largest part of our everyday distribution is our random stone for patios, sidewalks and pool decks. However, we have one of the largest sawing facilities in the state. We have custom built saws plus guillotines so we can cut anything, from the smallest one-piece order to the largest of commercial projects. We cut dimensional and chopped stone to include but not limited to; wall caps, hearths, mantels, pool coping, tables, benches, counter tops, stair treads or even your custom template. We can saw cut, snap cut, radius cut, bull nose, miter or hand chisel to give your project that custom professional look that you want.
