Granite is an igneous rock formed from liquid magma, cooled slowly to form a substance approaching the hardness and durability of diamond. Its hardness and density comes from the fact that it has been solidified within the earth under extreme pressure. It consists of feldspar, quartz, mica, and other minerals that all contribute to the unique coloration and texture of each granite deposit. Granite is considered an ideal choice for kitchen countertops because it can withstand high heat (up to 1,200 degrees Fahrenheit). Granite countertops are virtually scratch-proof and will not scratch even when directly cut on.

The density and weight of stone will vary from color to color. Most of the granite we stock is 3 centimeters (1 ¼ inch) thick and weighs between 16-22 pounds per square foot.
