Montana agate is usually a creamy light yellow to almost clear color with embedded moss structures in varying shades of brownish red to black. This agate is also referred to as "moss agate" (an agate that has colored inclusions that may resemble moss) or "scenic agate". Most are found in gravel deposits from the Pleistocene age (10,000 - 1,6000,000) in the area of the Yellowstone River and its tributaries. Along with sapphire, it is a state gemstone for Montana.
One of the most attractive features of Montana agate are the colored inclusions, made up of minerals such as iron and manganese. These inclusions form when mineral rich water moves into the rock through cracks or fractures and the minerals in the water are deposited within the stone.
