About

Green Country Stone is a natural stone quarry located in Eastern Oklahoma.  We currently supply stone to yards in 31 states across the U.S.  We offer a wide variety of materials including Building Stones, Patio Stones & Landscape Stones.

GCS started in 1990 with 1 Quarry, and we’ve been growing ever since.  We now quarry out of 5 different pitts which produce a large variety of stones available in many different colors, textures, shapes, and sizes.  Our Rock Island Quarry is a large producer of “Hackett” material.

GCS is a wholesale company that sells to stone yards.  We don’t offer exclusives, but we do our best to protect our customers.  If our stone is represented on a yard in your area, we will guide you in the direction of who you need to contact to get the materials you are looking for.  If there is not a yard in your area that carries our products, we will make every effort to help you get the stone you need.
