Madison Gold 3/4" sized goes through a similar process as screened rocks but contains even less dust, fines, and small particles. The Earth-colored granite is a large, clean grade that is also a byproduct in the creation of sand. Madison Gold is popular for use outside of homes in the North Valley and across Arizona. In addition to the tan stones, Madison Gold features small bits of mica to texturize the blend and allow it to shine in the desert sun.
