Oklahoma Stone’s Iron River Stone is from a new quarry that we have for this year. It is a very adaptive stone which is very solid and colorful. It is a great stone for any Landscaping or Building Project. Plenty of it is available in 1 and 2 inch Lay Down, and Standup Slabs, 4 inch chopped and 2.5 and 3 inch thick Squares and Rectangles.
