<p>Natural stone counter tops and methods for making and using the counter tops are described. The counter tops are made from natural stone, including granite, but comprise prefabricated pieces that are substantially modular. The pre-fabricated pieces are manufactured with an integrated edge so that they can be quickly assembled to create a counter with an integrated exterior edge, without the need to make and install a separate exterior edge. The prefabricated pieces can be quickly manufactured and easily stored as inventory, allowing the counter tops to be quickly and easily installed without the wait and cost of custom ordering the counter tops.</p>
