When you think of luxury and stone, you think of marble. Marble is basically metamorphosed limestone. Once limestone is subjected to heat and pressure, the calcium carbonate re-crystallizes into marble. There are several types of marble; calcite, dolomite, serpentine and travertine. Each of these is similar in their composition, that being predominately calcium carbonate, and their capability to take a polish. Marble makes stunning countertops that will make your kitchen the star of your home.
